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.
Suitable for internal or external use but maintenance instructions must be followed to preserve the finish of your product.
