Installation dimensions and interfaces

Catalogue backset E is 25 mm; faceplate width is 14 mm. Check the two dimensions separately; Measure faceplate width between the left and right outer edges; check the actual backset installation reference against the complete model drawing, without substituting door thickness.

The oval cylinder's profile and fixing method must be matched separately; a euro-profile cylinder is not a direct substitute.

Locking and operating conditions

This model has backset 25 mm; the key can operate the latch. Bolt locking has 1 throws; check the 69 mm centre distance together with the existing cylinder and handle positions.

Additional bolt projection is 4.5 mm; the door gap and strike plate must provide clearance for the projecting portion; this value is not the total bolt travel.

Limitations

• Check overall faceplate length, fixing-hole positions and actual strike-opening dimensions against the full installation drawing; the faceplate-width diagram is not a drilling template.
• The catalogue's electric-model voltage and current do not apply to the mechanical construction on this page; this page does not infer a fire rating or a security grade for the complete door.
