ASEC AS15 & AS19 Deadlocking Nightlatch

The Asec AS15 & AS19 Deadlocking Nightlatches are robust, double-locking lever-action rim locks designed to provide reliable security for residential and commercial doors. The AS15 model features a compact 40mm backset, while the AS19 model offers a standard 60mm backset.

These nightlatches operate via an internal lever handle to withdraw the latchbolt, or by key from the outside. For enhanced security, full deadlocking is achieved by a reverse turn of the key from the outside, which locks the internal handle to prevent unauthorised entry or bypass. A convenient snib button on the lockcase allows you to hold the latch back in the open position or lock it in the closed position.

Available in a wide range of case finishes - including Black, Brasslux, Dull Metal Grey, Polished Chrome, Satin Chrome, and White - and with Polished Brass or Satin Chrome cylinder options (as well as "Case Only" variants for use with your existing cylinders), you can easily find the perfect match for your door. Please select your required backset, finish, and cylinder options from the selection below.
