How to Identify Your Multipoint Lock

To identify your multipoint lock you will need to answer 7 essential questions:

1) Which Manufacturer?

2) Backset?

3) Centres?

4) Locking Points?

5) Distance between locking points?

6) Faceplate?

7) Lock Operation?

Below we will guide you through each of these questions. Once you have all the information you can use our handy "Refine Search" function on the Multipoint/UPVC Door Locks page to narrow it down to the exact lock you need.

1) Which Manufacturer?

Check the faceplate and the gearbox on the lock for the manufacturers name or logo. If there is no logo stamped on the faceplate or gearbox, it is likely that the lock is manufactured by ABT, Millenco, Weru or it is an older version of Fullex of KFV. To help you find the right lock where no logo or name is present we have collated images of all the multipoint gearboxes currently available on this site to help you find the right one. See Multipoint/UPVC Door Lock Manufacturers Guide.

2) Backset

Measure the distance from the front of the faceplate to the centre of the Euro cylinder cut out. This is shown as measurement A on Fig 2.1 below. NOTE: This measurement is from the faceplate of the lock NOT the edge of the door as there is often a lip on the edge of the door or the faceplate is recessed slightly into the edge of the door.

3) Centres

Measure the distance from the centre of the spindle hole to the centre of the top part of the Euro cylinder cut out. This is shown as measurement B on Fig 2.1 above. Measurements are taken to the middle of the locking point but allow for 5 - 10mm for accuracy and depending on whether the locking points are fully engaged.

4) Locking Points

Note which locking points you lock has and the order that they are fixed to the strip. Locking points could be any one of the following:


Roller Cam	Mushroom Cam	Hook	Deadbolt	Finger Bolt/Pin	Wedge Bolt

5) Distance between Locking Points

Measure the distance from each locking point on the strip to the centre of the spindle. These are marked as C, D, E & F on the diagram below. When comparing your measurements to the measurements provided on this site, you will most often need to add C & D together (Inner Locking Point) and E & F (Outer Locking Point) together. Only the Outer Locking Point is available in the "Refine Search" function.

6) Faceplate (Sometimes referred to as the forend)

a) Measure the width of the faceplate in mm.

b) Check to see if the faceplate has a round, flat or u-rail profile.
