These Brass Mushroom Door Knobs are a beautiful example of a very traditional design. Suitable for both mortice or rim locks and latches. Available in 2 sizes making them perfect for all different sizes of door.
The polished brass is left unlacquered and will develop an aged patina and darken with time.
These brass mushroom 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. They are supplied with 2 spindle lengths - 120mm for use with rim locks and 100mm for use with mortice locks and latches. For best results we recommend using a Heavy Duty / Heavy Sprung lock or latch, with at least a 100mm lockcase 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 with matching screws. Always use a pilot drill.
