You are measuring the overall width and height of the door including the door, the frame and cill.
- WIDTH: Measure in 3 points; top, middle and bottom and take the smallest measurement and deduct 10mm.
- HEIGHT: Measure again in 3 points; left, centre and right and take the smallest measurement and deduct 10mm.
- DIAGONALS: Ensure the opening is square by measuring the diagonals. There should be no more than 5mm difference between each measurement.
This is the most common. You have a lever handle to open and close the door from both sides. You lift the handle up to throw all the multipoint locks and turn the key to lock. To unlock turn the key and push the handle down to open.
Pros — Easy grip and you're in control of locking the door and won't get locked out (unless you lose your key)
Cons — if you forget to turn the key its not locked and someone can just the push lever down and walk in.
The Lever Handle is inside with a pad handle outside, the difference being the handles are independent of each other.
Pros — if you pull door to from inside it locks on the latch, so no one can follow you in, or if you forget to lift handle and turn the key on way out it is locked on the latch.
Cons — if it slams shut behind you and you don't have keys you are locked out.
These locks are generally designed for pull bar handles but can be used with a knob and finger pull. They don't have level handles; they have multipoint latches. To lock from inside you turn the key or thumb turn to wind out the deadlock. Externally you pull to and all latches engage, and you turn key to deadlock.
Pros — no level handle, pull door to and its locked by the multi-point locking system
Cons — if it slams shut behind you and you don't have keys you are locked out. If your grip isn't so good, turning the key inside to lock can be fiddly.
They are all, equally security rated when locked, it's a user preference and door style choice, please make sure you choose the best option for your needs.
