Prestbury Mortice/Rim Knob Sets
Our prestbury mortice/rim knob sets are available in two sizes, the larger of the two is a great choice for more substantial or feature doors. Manufactured from either solid brass or solid bronze resulting in a heavy, chunky product with a symmetrically classic design to both the knob and rose.
Aged Bronze Finish - (For Internal or External Use)
This finish is manufactured from solid unlaquered bronze containing a minimum of 85% copper. Our aged bronze is matt and rich due to the finishing process we use to age the metal, this process initially darkens the material, however this finish will gradually oxidize over time revealing the warm copper undertones. Lightening the finish can be accelerated by hand-polishing with a heavy dry cloth. This finish has been salt tested to 480 hours, which meets grade 5 British Standard.
