Victorian Unsprung Rim Knobset

The Victorian Unsprung Rim Knobset is a face-fix mortice knobset designed with a Victorian style mushroom knob profile. It features an unsprung mechanism, which means the knob does not return to its original position automatically after operation. This knobset is available with a rose diameter of 56mm and a knob diameter of 52mm. The projection from the mounting surface is 70mm. The product is offered in multiple finishes, including Brass, Chrome Plate, and Satin Chrome.

This rim knobset is typically fitted to internal doors equipped with a rim lock or night latch that accepts a knob spindle and is compatible with face-fix installation methods. The unsprung design makes it suitable where the knob is used solely for operation of the latch without the need for spring return.
