These Polished Chrome 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.
Polished Chrome - made from a base of solid brass coated with a durable chrome plating to give an exceedingly high-sheen finish. Favoured for its bright, bold appearance, Polished Chrome is well suited to contemporary designs and offers a smooth, mirror finish when polished. This works best if a cool, clean look is desired.
Note – Do not use chemicals or cleaning products as it may affect the plated finish. An oily cloth can be used to wipe over the product from time to time to remove any harmful deposits that build up on the surface of your product, this will also aid protection against any environmental elements. For persistent marks the use of a good quality metal polish for silver finishes can used. Oiling moving parts during installation and periodically afterwards will help to aid protection against exterior and environmental elements.
These 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 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.
Sold in pairs. Supplied with matching fixings. The screws supplied are hand finished, so please take care when fixing. Always use a pilot drill.
