Construction and operation of this version
152862700 is an explicit ordering row in the 52862 series with backset 70 mm. The round-ended faceplate version with function A explicitly lists an anti-manipulation mechanism in this model section; Outside operation is by key only; inside operation can use a handle or escape device. Without a description of automatic action, the door-closing bolt action of adjacent 52840/52860 must not be assumed.
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.
