The Alexander and Wilks Kershaw Door Knobs are exquisitely crafted from solid brass at exceptional prices. They have a traditional mushroom shape that has been created using classical British designs and the design and finishes of this Mortice Door Knob have a look and feel that is well suited to modern and traditional homes, apartments, offices and commercial buildings. As this is an Unsprung Knob, we recommend using a double sprung latch. Available in two sizes; 41mm and 51mm. Alexander & Wilks represents the very best of architectural hardware and ironmongery. Using both time-honoured craftsmen's skills, combined with the latest computer-aided precision manufacturing, results in a collection of beautifully made items with flawless results.
