Our knobs come unsprung having a normal weight feel (hollow) and have loose roses to enable them to be used with a rim lock (discard one rose) or use with a mortice lock.
They have 8mm threaded spindle to take adjustment for various door thickness and lock firmly with a grub screw. The GRUB SCREW should locate on the ''V'' in the shaft and not on the threaded part.
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.
