Fitment & What to Check

When installing the Alexander & Wilks British Standard 5 Lever Mortice Deadlock, confirm the door has the correct mortice pocket to accommodate the 150mm case height and 48mm centres.

Ensure compatibility with the 8mm follower size for handles or thumbturns if applicable. As this lock is non-handed, check door handing but no reconfiguration of the lock is necessary.
