Description
The Carlisle Brass M35 mushroom rim knob set will fit all the rim locks we sell. The knob is available in two sizes; a 52mm diameter knob on a 56mm diameter rose or a 57mm knob on a 64mm diameter rose. Full mortice knob sets are also available refer to related products.
Complementary Door Finishes
To complement or match the finish of the rim or mortice lock the mushroom knob set is available in three finishes, polished & lacquered brass polished chrome and satin chrome. Other finishes are available to special order.
Threaded Spindle Knob
To ensure a positive location on the lock the spindle is pinned onto the rim side knob and threaded. This allows the knob to be positively fitted to the rim lock through the door, eliminating the usual looseness of rim lock knobs. Once the rim side knob is firmly attached the non-rim side knob is attached to the door, over the exposed spindle.
