Intended function of this model

For doors that need to remain locked after closing; the catalogue specifies 21 mm latch projection.

This page records a distinct catalogue model; for the actual delivery configuration, confirm whether the cylinder, escutcheons, handles and striking plate are included.

What to check when reading the parameters

When replacing an existing lock case, first check the door-edge faceplate, mortice and cylinder/handle positions, then compare bolt functions. Adjacent model numbers or identical finish codes do not establish direct interchangeability.

Edition and supporting documents

The original source is the official mechanical lock case catalogue, page 23. When requesting updated information, provide the full model LC120, and separately confirm the cylinder system, striking plate and installation drawing revision. Models with microswitch suffixes are not treated here as parameters of the base model.

Limitations

This is a record from an official historical catalogue and does not indicate current sales, stock or the latest configuration; confirm the model's status with the manufacturer before purchasing.
Finish and accessory codes follow the original source; dimensions have not been inferred from diagrams, and no fire, exit or grading certification conclusions are provided without verification of the door assembly.
