Since doors are an integral and important part of a home, it is absolutely essential to ensure that they look the best and function efficiently. Therefore the right locks and latches need to be chosen.
It is also important to consider what you will want to use on your doors when choosing the doors themselves, as some lovely modern door designs are unfortunately not practical if you want to use door knobs.
The 2 main lock and latch case depths available for lever handles are 64mm (2 ½”) and 76mm (3”) which are perfect for lever handles which sit towards the edge of the door. Most door knobs will physically fit on these locks too, however depending on the diameter you can be left with very little space between the door frame and the edge of the door knob to accommodate your knuckles.
On locks suitable for lever handles, the keyhole, cylinder and bathroom turn will sit directly below the lever handle. These are known as ‘vertical’.
The 3 main lock and latch case depths (international standard) available for door knobs are 102mm (4”), 125mm (5”) and 152mm (6”). With these depths, the door knob sits comfortably away from the edge of the door, eliminating the risk of catching the knuckles.
While lever handles can also fit on these locks, it may look odd and is not usually recommended
On locks suitable for door knobs, the keyhole, cylinder and bathroom turn will sit next to the door knob at the same height. They are called ‘horizontal locks’.
Following the above, the next important question that you can have is whether the fixing method of the lever handles and door knobs matter
Well, it does!
If your handles or knobs use a fixing method that can be described as “back to back” fixing, it is essential that you choose a case lock or latch case that allows for these back to back bolts to pass through it. If the method of fixing door knobs is a ‘back to back’ fixing, it is important that you choose a case lock or latch case that allows for these back to back bolts to pass through it.
