Glass Ball Mortice Knob

A set of solid brass mortice knobs, featuring unsprung design, with an additional glass ball knob. Comes complete with bolt-through screws, an 8mm spindle, and grub screws. It’s advisable to use larger mortice latches to match the size of the rose. These knobs are suitable for fire-rated solid wooden doors and are easy to clean due to the glass construction. They are ideal for both commercial and residential applications.
