LOCKS & SECURITY
Below is a list of just some of the items we work on.
There are two basic types of safety stays which stop small people (children) falling out the window and makes it a 100% more difficult for uninvited big people coming in. If you wish to close a window more securely than this then see sash locks below. Both types can be fitted to both awning and casement opening windows. If you like to leave your windows open on the second tongue of double tongue window handles then safety stays are a must. (Some insurance companies will not pay out a claim if the window was just left open or on the second tongue there must be evident of forced entry.)
Stainless steel restrictor stays that are permanently fixed one to each side of the window sash (they come and we sale them as a pair) and when the window is closed you can’t see them. Once fitted the maximum the window sash can open is about 100mm. This type of safety stay would be the most popular and user friendly in terms of operation. Its biggest draw back is you can not get egress from the window once these are fitted however you can do with the Security Stays listed below.
Security Stays these have the three notches and are surface mounted meaning when the window is closed you can see the security stay. They can be unhooked in the closed position so the window can then be opened wide if required. In general use they are not as user friendly as the restrictor stays because every time you use them the stay drops into the next notch usually on one side so opening the window becomes a jerky affair however if you wish to be able to open the window all the way for emergency egress etc then these will do the job. Again the recommendation is one on each side of the window so that is two per window so our pricing is per pair they are sold retail as per each. This type of security stay can also be fitted to timber joinery.
These are a small deadlocks fitted to your opening window sash they can be key locked or knob turned locked. When locked with a key you have to use a key to unlock it, if locked by turning the knob then you can unlock it by turning the knob. They can be all keyed alike so you only need one key to lock or unlock any number though out your house.
Sliding Window Locks:
These are a small deadlock for sliding windows. They can be locked by key or by press button. Press the button again to unlock it or if locked by key then you need to use a key to unlock it. These can also be setup to lock the window partly open for air but still very secure. They can be keyed alike to other locks in the house.
Window Press Lock:
This is a compact lock with a short bolt for both Aluminium and Wooden Joinery again with keyed alike option.
Locks Sliding Doors
Sliding door locks come in two basic types you have the Sliding Door Lock which is the handle lock that you close the door with and there is Patio Bolts plus a third Commercial sliding door locks.
Sliding Door Locks:
Sliding Door Lockscome in a number of different configurations brands and setups we recommend the Albany brand that comes in a number of different key formats and handle options but they all have the double hook and anti slam setup.
Albany non keyed; this lock has a D-handle on the inside with a lever snib under it to operate the double hook locking mechanism and an external slim pull on the outside.
Albany keyed; this lock has a D-handle on the inside with a lever snib under it to operate the double hook locking mechanism and a external slim pull on the outside with a key in it to operate the double hook locking mechanism.
Albany Deadlock Double keyed Daylatch; this lock has a D-handle on the inside with a lever snib under it to operate the double hook locking mechanism plus a key in the middle of the lock body and a external slim pull on the outside with a key in it to operate the double hook locking mechanism. When locked with the key you have deadlocked the door so no one can go in or out without unlocking it with a key. If you lock the door using the snib (Daylatch) from the inside then you only need to use the snib to exit but from the outside you will need a key to enter.
Albany slim pull both sides; slim pull on inside with key instead of the D-handle and snib lever the key has a knob on it called a securiturn which operates the double hook locking mechanism. The outside has the standard slim pull and key.
Albany mortice lock; They have similar configurations as above except the lock body that holds the double hook locking mechanism is not surface mounted under the handle as in the above locks but is morticed into the edge of the aluminium extrusion like a normal hinge door lock where you have the tongue of the lock coming out of the edge of the door. The advantage of this setup is rods can be attached to these locks which run up and down inside the door extrusion which creates a situation where the door is locked from three places in the middle by the handle and in the top and bottom making for a very secure door.
Patio Bolts are fitted to normally the inside of a sliding door at the back top they one prevent the door from being slide and second stop it from being lifted. When we fit these we often put a second hole so the door can be bolted in the open position to give air recommended for when you are in the house it just stops someone from walking though an open door uninvited. There are a number of different versions of patio bolts but all have a bolt lockable by key some are small and some are large but all do the same thing. (Note: they can also be fitted to hinge doors see locks hinge doors.)
Commercial Sliding Door Locks:
Commercial sliding door locksare all very similar they have a large strong hook tongue that flips out of the lock body that is morticed (housed) into the leading edge of the door hence the lock body is inside the door extrusion and is operated by a key cylinder that is inserted into the lock body from the outside face of the extrusion. This key cylinder from the outside is operated by key but on the inside it can be either a key or a thumb turn. There are two types of strikers; a striker is the part that the hook goes into to attach its self securely to the frame, one is a fixed no moving parts and the other has a spring loaded catch that holds the hook. There is no handle to this lock so handles are separate and come in many shapes and sizes usually in a D-handle format often off set to give more hand clearance.
Locks Hinge Doors
Hinge door locks come in many different types all with their own unique options so we will cover the main ones found in most homes and can be on wooden or aluminium joinery plus some info on commercial ones and a couple common ones used mainly on wooden doors.
Knob Sets or Entrance Handle Sets:
Exterior Doors; Entrance Handle Sets or Knob Sets come in a number of different shapes but follow the same basic setup with a key in the middle of the knob on the outside and a push button or turn button in the middle of the knob on the inside. The knob handle when turned pulls the retractable tongue of the lock on the edge of the door back so you can open the door when released the tongue pops back out again. These locks work by pushing in the button or turning the button on the inside going out and closing the door and it’s locked.
This type of lock can come with a lever handle instead of a knob and we can change a knob set over to a lever handle it still has a key in the middle of the outside handle and a push button on the inside but rather than a knob to hold onto you get a lever handle which is great for arthritic or elderly people who have trouble turning a knob handle.
Interior Doors have similar looking locks without the key option and for bathroom toilet situations they have a privacy button on the inside and a emergency release hole in the front. So the standard internal one is called a passage set and the bathroom or toilet one is called a privacy set with just the knob for a wardrobe called a dummy set.
These exterior and interior locks can come in different backset sizes the backset is the measurement from the edge of the door to the centre of the handle in this type they come in 60mm, 70mm, 95mm and 127mm.
The humble common aluminium back door; the lockis often a push button 127mm backset entrance lock in the centre rail of the door often with a cat door in the bottom glass and is next to a small window that is over the laundry tub. This lock setup works fine to stop the door from blowing open from the wind however from a security point of view it has three problems:
a) The lock can be reached though the cat door and undone. (ask the kids)
b) The window next to the door can be popped open then you reach across and undo the lock.
c) Any one who has entered the house from some where else and wants to leave by the back door carrying what’s not theirs can just open the door from the inside.
Fitting a Patio Bolt to the inside of this door solves all three of these problems unless you use this door to come and go by in which case you can’t access the patio bolt from the outside.
To solve this problem you have three options:
1) Replace the existing key and push button lock with a keyed both sides lock. This lock has a key instead of a push button on the inside which means it opens and closes as per normal but each time you wish to lock or unlock the door you need a key. The retractable bevelled tongue on these locks is about 12mm.
2) Replace the existing lock with a retro fit Lever Handle Double Throw Horizontal Mortice Lock now that’s a mouth full. This lock is designed for this problem the lever handle acts as per a normal open and close latching lock set however put the key in and turn it twice and it throws the short 12mm latching tongue out to make it a 25mm deadbolt. This lock goes inside the centre rail of the door replacing the existing lock.
3) Leave the existing lock and fit a commercial type key operated deadbolt into the vertical stile above the only catch with this is if your vertical stile is deep enough to take this lock if it is then in our opinion this is a very secure option and great value for money.
Tubular lock Set: (and decorative grip sets)
For all intents and purposes these are the same as the entrance handle sets above they have a different internal setup and some have external screws showing on the inside to hold the outside and inside handles together because of this screw together difference they also come in the decorative grip set option this is the entrance lock with the big D-handle and push thumb button on the outside of your main entrance door and either lever or knob on the inside normally with a deadbolt fitted above.
Internal doors have similar looking locks without the key option and for bathroom toilet situations they have a privacy button on the inside and an emergency release hole in the front. So the standard internal one is called a passage set and the bathroom toilet one is called a privacy set with just the knob for a wardrobe called a dummy set.
All these locks can come in different backset sizes the backset is the measurement from the edge of the door to the centre of the handle in this type they come in 60mm, 70mm and 127mm.
Lever Lock Sets:
As the name suggests they have a lever handle mounted on an oblong face plate often with a lock cylinder underneath the handle in the same face plate but not always. The body of the lock in housed (morticed) behind the handle face plate inside the door stile. This type of lock is found in most homes say built in the last ten years usually on exterior hinged doors like French Doors, Entrance Doors, Store Room Doors and the third panel in a Bi-fold Door setup. They come in three basic types plus some variations we will cover just the basic ones.
1- Point: First one has just a retractable tongue only with a key that will lock the tongue. This is called a 1-point lockset.
2 – Point: Second one has the retractable tongue plus either a drop down bolt (long throw) or push out bolt (short throw) this makes it a 2-point lockset.
4 – Point: Third one has the retractable tongue plus either a drop down bolt (long throw) or push out bolt (short throw) as well as locking rod/bolts running inside the stile going out the top of the door and bottom of the door. This is called you guessed it a 4-point lockset.
All these locks can come in different backset sizes the backset is the measurement from the edge of the door to the centre of the handle or key hole in this type of lock there is a narrow backset found in older doors 25mm then newer doors they go 30mm, 40mm and 50mm.
Wooden Doors; The standard deadbolt keyed both sides (or thumb turn inside key outside) with a 25mm bolt that has a hardened anti cutting pin though the centre of it is normally put in a wooden door because the 60mm backset will not let it fit into the aluminium vertical stile of most types of aluminium joinery. However for a wooden door that only has a normal push button entrance lock or the old legge one key fits all lock adding this type of deadbolt gives great security and value. These deadbolts have an adjustable backset either 60mm or 70mm you normally set it to match the existing entrance lock already on the door the backset is the measurement from the edge of the door to the centre of the handle or key hole.
Aluminium Doors; The most common deadbolts for aluminium doors are:
Lever Handle 2 – Point: has the retractable tongue plus either a drop down bolt (long throw) or push out bolt (short throw) this makes it a 2-point lockset with the drop down or push out bolt being the deadbolt part.
Lever Handle 4 – Point: has the retractable tongue plus either a drop down bolt (long throw) or push out bolt (short throw) with the drop down or push out bolt being the deadbolt part as well as locking rod/bolts running inside the stile going out the top of the door and bottom of the door. This is called you guessed it a 4-point lockset.
Replacement fit Double Throw Deadbolt; for aluminium door with a push button lock in the centre rail is called a Lever Handle Double Throw Horizontal Mortice Lock now that’s a mouth full. This lock is designed for this problem the lever handle acts as per a normal open and close latching lock set, however put the key in and turn it twice and it throws the short 12mm latching tongue out to make it a 25mm deadbolt. This lock goes inside the centre rail of the door replacing the existing lock.
Deadbolt 23mm short backset: Leave the existing lock in the door and fit a commercial type key operated deadbolt into the vertical stile above the existing lock. The only catch with this is if your vertical stile is deep enough to take this lock if it is then in our opinion this is a very secure option and great value for money for securing an existing aluminium door.
Door viewers are a small spy glass that lets you see who is on the other side of a door before you open it. The viewer is installed at eye height in the middle of the door.
Digital Locks Mechanical:
This type of lock has a mechanical key pad on the outside with a knob beneath it once the right code is punched in you turn the knob which pulls the retractable tongue back and you can open the door. Normally it has a lever handle on the inside which you just pull down to open the door. The combination is changeable.
Patio bolts can be fixed to the inside of hinge doors both timber and aluminium normally at the top with the bolt going firmly into the door sill some people put a second one on at the bottom of the door especially on light framed aluminium panels.
Commercial Hinge Locks:
There are many different types of commercial joinery locks from the humble deadbolt we suggest to use to beef up the security of a back door if it will fit in the stile to specific locks for school class rooms with fire requirements etc. We have access to all of them including parts.
Wooden Door Locks:
There are a couple of common locks that are found on wooden doors worth mentioning.
Legge lock; this is a two lever it’s the lock you can buy keys for by the number from most hardware stores it has a lever handle. To upgrade the security we can replace these with a 3 and 5 lever version and we carry replacement springs for the handles. Another option is to put a deadbolt in the door and use the existing lock as a latch handle only.
Night Latch; this is the lock often used in front doors of older homes on the outside you have a D-handle with a circle at the top with a lock cylinder in it. On the back of the door you have a night latch lock body. The night latch lock body can come with a number of different options like tongue hold back and deadlocking by replacing the more simple version with more secure one you can greatly increase your security.
Deadbolt; is keyed both sides (or thumb turn inside key outside) with a 25mm bolt that has a hardened anti cutting pin though the centre of it is normally put in a wooden door because the 60mm backset will not let it fit into the aluminium vertical stile of most types of aluminium joinery.
As your joinery becomes a little older and things start to wear and even newer homes with building movement etc locks can get out of alignment and jam the worst thing to do is force it or slam it as this could increase the problem. Give us call we’ll sort it out. If you get onto it right away it quite often just needs the door re-squaring up or the lock striker plate adjusting. However if it needs replacing we carry a comprehensive range of Knob sets and lever handle locks and parts.
