Ingersoll SC71/SC73 Ten-Lever Classic Nightlatch

The Ingersoll SC71/SC73 Classic Nightlatch is a legendary high-security rim lock that has remained largely unchanged for over 40 years. Known for its exceptional build quality and reliability, it continues to be a popular choice for front doors in residential and commercial settings alike.

This model includes a 10-lever high-security cylinder as standard, providing outstanding protection against picking and manipulation. The lock features auto-deadlocking every time the door is closed, and offers a double locking function via key on the SC71 variant for added external security. The SC73 includes the same robust mechanism but without the external double lock feature.

A convenient hold-open function is available using the internal snib. All locks are supplied with a matching cylinder, striker plate, fixings, and 3 high-security keys. Please note, for security purposes, the word “Ingersoll” is no longer embossed on the cylinder casing.
