Construction and operation of this version

152310450 is an explicit ordering row in the 52310 series with backset 45 mm. Check the 2-throw bolt configuration together with the 22 mm faceplate width. This ordering section does not list handle centre distance; the 85 mm centre distance of the latch version on the same page is not applied to it; match locking components and strike plates by model.

How to check installation dimensions

This model's backset is 45 mm, the distance from the specified door-edge faceplate reference to the operating axis. Faceplate width, centre distance and external lock-body depth describe different directions and must not substitute for one another.

For replacement, record the old lock's full number, faceplate-end shape, inside and outside operating components and strike positions; when changing handing or linked rods, confirm interfaces according to the product instructions.

Limitations

• Series certification and catalogue descriptions of fire or escape applications do not mean this model meets current requirements when installed in any door assembly.
• Check accessories against the corresponding model and installation instructions; Cylinders, rods and escutcheons listed as available on request are not standard equipment.
