This is Knobbles and Bobbles' stunning pair of cut glass mortice knobs in black glass.
The diameter of these knobs is 6cm as is the diameter of the rose and they will fit doors that have a thickness of between 33mm and 40mm inclusive. All our mortice knobs are supplied with the connecting metal spindle.
The knobs are sprung and are compatible with mortice mechanisms. Not rim locks though, sorry.
** The spindle will need to be cut to the correct length for your door depth **
