Heritage Brass - Mayfair Mortice Door Knobs - Unsprung

Heritage Brass Mayfair mortice door knobs (unsprung) feature the Mayfair design on a round rose and are intended for internal doors where a sprung return or locking function is not required. The unsprung configuration means the knobs do not return to a horizontal position automatically.

These mortice knobs are supplied as a pair and include a spindle and the fixing screws and fasteners shown for the example variant. They are suitable for use with a heavy duty UK tubular latch when replacing existing knobs; for new doors a tubular latch (reference YKAL3-AT) is shown as a required additional purchase in the example variant. Example dimensions: projection 76mm, maximum diameter 64mm. A 10-year mechanical warranty on the mechanism is listed for the example variant.
