Retrofitting a smart handle is simpler when a suitable mortice can stay in the door. The BBLN32B is made for that job, replacing the lever hardware while retaining most compatible lever and cylinder mortice locks.
The compact rose format is useful in occupied homes, offices and guest rooms where extensive door cutting would be disruptive. Users still receive individually managed access and an activation record through TTLock.
No new mortice lock is added to this product, so the variants are colour only. Confirm the existing spindle, cylinder and backset arrangement before ordering, and allow separately for any escutcheons the door requires.
Important: This retrofit handle does not include a mortice lock. Confirm the existing mortice, spindle and cylinder arrangement before ordering. Escutcheons and an 80 mm barrel/cylinder are not included.
Measure from the front edge of the door to the centreline of the existing handle spindle or cross-bore hole. Use the result to confirm the installed mortice geometry before ordering. The diagram illustrates the same backset principle in inches.
