Our knobs come unsprung. They are solid cast, not hollow, roses are attached so use in conjunction with a mortice latch or lock.
The knobs are surface fixed and for best results the centre of the knob should be a minimum of 3inch from the edge of the door. Heavy Duty latches 4inch or 5inch are recommended for maximum efficiency.
Supplied with necessary fixing screws.
