Construction and operation of this version

15C150700 is an explicit ordering row in the 5C150 series with backset 70 mm. The bathroom lock with a square-ended faceplate has a single-throw bolt, unlike the two-throw cylinder-operated version in the same series. Check the inside and outside privacy controls and centre distance; do not mix versions solely because their backsets match.

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

• The spindle dimension is specified only in section 5C170; it has not been automatically applied to 5C150.
• 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.
