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