Dimensions and installation orientation

For this model, A=32.5 mm, B=10 mm, body L=42.5 mm; Section A is 22.5 mm longer than section B. Tabulated nominal size 33/10 identifies the order; use columns A, B and L for actual lengths.

The original drawing divides the sections at the central fixing-screw axis, with section B on the left and section A on the right. Determine orientation from the escutcheons on both door sides and the operating method; page-left and page-right do not establish inside and outside.

Operating construction and matching components

Key operation on one side; section B is fixed at 10 mm, with a cam adjustable to 8 positions. Check the cam position required by the lock body and the key-side projection; this is not a cylinder accepting keys on both sides.

This model has a cam adjustable to 8 positions; check cam position and lock-body compatibility together with length.

Limitations

A and B follow the orientation of the manufacturer's original drawing and do not directly designate the inside or outside of the door; check the operating side before installation.
Catalogue nominal sizes differ from actual measurements; adding nominal sizes must not replace L.
The original diagram shows only the lengths of the body sections; it is not a product outline, shaft-end machining drawing or installation template.
