Construction and operation of this version

152751700 is an explicit ordering row in the 52751 series with backset 70 mm. The passage version provides only a latch, operated by handles on both sides. Model rows without bolt-throw or cylinder-centre-distance values must not inherit these parameters from other heavy-duty locks.

How to check installation dimensions

This model's backset is 70 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.
