A heavy-duty 5 lever, kite marked sash lock for use with any of our 'Unsprung' lever lock handles or knob sets. When choosing an 'unsprung' product there is no spring inside the handle/knob therefore it relies completely on the spring inside the lock/latch. Can be used with any of our door furniture and is a great match for all pewter, chrome and nickel products. Complies with British standard and comes complete with all necessary fixings.
