Frequently Asked Questions
- Does this lock include the euro cylinder?
No. This is the lock body and strike. A compatible euro fixed cam cylinder must be supplied separately. - What does 48 mm pitch mean for installation?
Pitch is the centre distance between the spindle and cylinder. This lock uses a 48 mm pitch, so it must match the existing door preparation and handle set requirements. - Can this be used to replace older lever locks?
It is intended as a retrofit option for many common lever lock preparations, but the correct fit depends on the existing cut-out, backset, and pitch. Confirm measurements before ordering.
Additional Information
- When retrofitting, the most common mismatch is pitch. Measure from the spindle centre to the cylinder centre and confirm it is 48 mm before committing.
- If the door has been swelling or dropping, the latch may bind even with a correct lock. Check door and frame alignment before adjusting strikes.
- Where restricted keying is used, confirm the cylinder cam type is fixed cam and that the cylinder length suits the door thickness and escutcheon thickness.
