How to Measure for a New Door Handle
Be sure that it fits
Not all handles fit all multi-point mechanisms. Before ordering, check the distance from the centre of the spindle to the centre of the cylinder barrel (PZ) and the distance between fixing screws.
Handle Measuring Guide
There are only two measurements that are required to ensure the full working operation of your new uPVC door handle. The first one is what is known as the PZ measurement. This measurement is the distance from the centre of the keyhole to the centre of the handle lever or spindle hole. This is measurement B on the technical diagram.
The second measurement is the distance between the two fixing points which are the screw holes on the uPVC door handles backplate. This is measurement F on the technical diagram.
If the above two measurements match up then the door handle will fit and operate perfectly. All other measurements on the door handle are mainly aesthetics and won’t affect fitting or operation if they’re different.
