Faceplate and installation dimensions

This model's backset E is 25 mm, the horizontal distance from the faceplate reference to the cylinder operating axis. Faceplate specification 290×24×3 mm must be checked together with the door-edge mortice; door thickness cannot replace backset.

This model has a flat faceplate; check length, width and thickness separately rather than replacing solely on similar appearance.

Locking construction and accessories

The 8 mm hook-opening clearance and 18 mm hook-bolt throw are distinct dimensions: the first concerns engagement position, the second locking movement. Throw cannot replace the hook-opening dimension.

This configuration uses Clip-in connection (clutch connection); do not interchange threaded rods directly with clip-in rods. Rods, auxiliary locks and striking plates form a matched system and must be selected from the original catalogue accessory list.

Limitations

• Striking plates and matching accessories are ordered separately according to the original catalogue; this page's dimension diagram is not a drilling or installation template.
• Confirm door handing, keep positions and complete installation requirements from this model's instructions.
