Installation dimensions and faceplate

This model has backset 25 mm and faceplate width 22 mm. When checking the door-edge recess, also confirm the actual fixing-hole and cylinder positions.

Locking construction and matching components

The laminated-steel hook must engage the corresponding strike plate; selection should focus on strike position and engagement clearance; a strike opening for a straight bolt is not an appropriate substitute.

This page describes a mechanically operated configuration; if a motor, hold-open device or electric strike is needed, check the applicable models for each accessory.

Limitations

  • The dimension diagram only explains the specified dimensional relationships; it is not a product outline, fixing-hole layout or installation template.
  • Check strike openings, connectors and suitability for the complete door system against the manufacturer's installation documentation for this model.
