Measuring Your Multipoint 
A:Backset
- Open the door so you can see the metal strip (faceplate) running along the edge.
- Get a ruler or tape measure that shows millimeters (mm).
- Place the zero mark at the flat front edge of the metal faceplate.
- Measure straight across to the exact center of the square handle hole (spindle).
- Write down the number in millimeters for when you buy a new lock
B: PZ measurement
PZ / Centres Measurement
The centres measurement, often called PZ, is one of the most important multipoint lock measurements. It is measured from the centre of the spindle
hole to the centre of the keyhole or euro cylinder position.
A very common size is 92mm, but many locks vary. Some locks use other sizes depending on the manufacturer and the handle arrangement.
Some multipoint locks have a split spindle or double follower. This means there may be two spindle positions or two different centre measurements on the same lock. For example, one very common split arrangement is 92mm / 62mm.
C: Steps to Measure Distances
- Find the reference point: Start your tape measure right at the middle of the square spindle hole (follower) in the center gearbox.
- Measure each point: Record the exact millimeters from that center spindle point to the exact middle of every top and bottom locking cam, hook,
or bolt.
- Note the point style: Write down what type of lock each point is (roller, mushroom, hook, or shootbolt).
- Record overall dimensions: Always double-check your main PZ dimensions and backset, as overall strip lengths depend heavily on those base sizes
Identify the Manufacturer
Check the faceplate and the gearbox on the lock for the manufacturer’s name or logo. There are hundreds of multipoint locks on the market. These are some of the more common gearboxes that are used.
