Frequently Asked Questions

Is this a complete lock?
No, this is an adaptor assembly only and must be used with a compatible Lockwood 3540 Series mortice lock.

Can this be used on sliding doors?
Yes, it is commonly used where the lock is mounted to the door jamb and engages with a strike on the door face.

Is this suitable for fire doors?
Suitability depends on the full lock configuration and compliance requirements. The adaptor itself does not determine fire rating.

Additional Information

  • Commonly used in Australian commercial projects requiring flexible mortice lock installation.
  • Often specified where standard lock positioning is not achievable due to door or frame constraints.
  • Incorrect adaptor selection can result in misalignment between bolt and strike.
  • Best installed by experienced locksmiths to ensure correct engagement and operation.
