MORTISE LOCK ASSA 2000 SYM

ASSA SYM two-system security lock with a latchbolt, a deadbolt and a thumbturn mechanism.
Backset 50 mm.
Hardened steel 3-layered deadbolt projects 21 mm thrown by 360° turn of key.
Thumbturn inside as an alternative function: makes it easy to lock and open the door when you are at home.
When leaving the house you can block the thumbturn with a nipple on the faceplate: the lock will stay in the security position and cannot be open without a key not even from inside. Opening the lock with a key automatically restores the thumbturn function.
Finish: Zinc.
