Lever pad UPVC door handles are found on some UPVC type doors and this signifies in some cases (not all) that the door can be closed without having to worry about key locking it when on the inside. A lot of customers ask us if they can convert from an inline single spindle handle to an off-set lever pad uPVC door handle and in some cases the answer is yes. What you will need to do is just take the handle off and observe if there is a second spindle hole about 20-30mm further down on the outside of the door. If your handle is inline you will need a split spindle lock.
Some lever pad UPVC door handles need to be fixed on the outside and used as a pull handle. This is the case where the lock itself rotates all the locking points as opposed to the uplift of the handle. The key would need to be turned 2-3 complete revolutions for the locks to work. These are great locks for security but are probably more rare nowadays. The stub spindle can be a good way to turn a lever or pad handle into a pull handle.
