Construction and operation of this version

156015700 is an explicit ordering row in the 56015 series with backset 70 mm. The 3-locking-point configuration and three-throw bolt action describe different features. For multipoint versions, also check extension rods and upper and lower strikes; a single-point construction must not be assumed to have rod interfaces.

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
