Frequently Asked Questions
Does the 1810 include cylinders?
No. The 1810 is plate furniture only. Cylinders and mortice locks are supplied separately.
Is this suitable for fire doors?
Yes, when installed with an approved Lockwood fire rated mortice lock and compliant door assembly.
Is this plate handed?
No. The plate itself is non-handed. Handing depends on the lock and lever configuration used.
Additional Information
The 1810 dual cylinder configuration is commonly specified in commercial environments requiring key access from both sides of the door. It is not a locking device by itself and must be paired with a compatible Lockwood mortice lock body and cylinders.
When specifying fire rated assemblies, confirm that the complete doorset, lock body, hardware and installation method comply with AS1905.1 and relevant project documentation.
