An attractive and well-proportioned Ebonised Beehive Knob Set in a rich, dark finish. Finished off with an Aged Brass Ribbed Rose. These ebonised beehive door knobs are Unsprung and have loose roses so that they can be used with both mortice or rim locks and latches. They have an 8mm threaded spindle to enable fine adjustment for various door thicknesses and lock firmly with a Grub Screw, which must locate on the V in the shaft and not on the threaded part of the spindle. For best results we recommend using a Heavy Duty / Heavy Sprung lock or latch, with at least a 100mm lock case to provide a minimum backset of 75mm. This is to make sure that the door knobs turn properly and return back to their start position. It also helps to make sure that you do not catch you hand on the door frame. Supplied as a PAIR with matching fixings. Always make a small pilot drill hole and use a manual screw driver to avoid damaging screws and finish.
