It operates in such a way that the 360 degree turn of key or thumb turn throws or retracts the hook-shaped deadlock and then 120 degree further turn retracts latch bolt as well. Cylinder may accept any standard 1-5/32" diameter mortise cylinder or thumb turn from either or both sides. Handle retracts spring-loaded latchbolt only.
