Mace's Rose

A type of door knob rose with a sleeve which extends over the neck of the door knob. The neck of the knob has a grub screw to fix it to the spindle (normally a Duce’s spindle) and the sleeve on the rose has a hole to access the grub screw. Once the grub screw has been tightened the rose is rotated so that the sleeve hides the head of the grub screw.
