Identify Your Ingersoll Lock

Over the decades Ingersoll Security have produced a number of different designs of locks. Many of which are still in production and can be ordered on this web site.

We have put together this useful guide on how to identify your particular Ingersoll Lock.

To the left we have shown the Ingersoll 'Classic' Nightlatch viewed from the inside with the door open. This lock would be if fitted to a single occupancy dwelling such as a house or a flat. The alternative model known as the 'Communal Door' Nightlatch looks identical but cannot be double locked from the outside. Shown here is a polished brass finish but polished chrome and satin chrome finishes are also available. The darker bronze finish is now discontinued. Beware of potentially faked items offered for sale at significantly lower prices on the internet. Genuine Ingersoll items can be ordered by clicking here.

To the right we have shown the outer view of the cylinder of either a 'Classic' Nightlatch or a 'Communal Door' Nightlatch. This particular cylinder has not been installed with the optional Cylinder Pull (see next picture). The cylinder can also be purchased separately and will fit either the 'Classic' Nightlatch or a 'Communal Door' Nightlatch.
