This Chubb Detainer Mortise Lock is supplied by Keys-Locks-Padlock as a Commercial or Domestic Mortise locking latch.

It is a high security 5 Detainer lock which Deadlatches, when the door is closed, it will work with a handle from the inside and a key from the outside,but will also lock with a key from the inside so that the handle will not open it.


The Chubb, 5 Detainer lock, with slam action locking and auto deadlocking latch bolt, is excellent security for entrances and fire escape doors, and can be used both for Commercial or Domestic use.

It uses a handle, (separate item) on the inside allowing access from outside by key only, the latch can be held back by the snib, on the handle, from the inside, if the door needs to be left in the open position.

The Chubb latch can be deadlocked from inside or outside, by key, this prevents the handle being operated from inside, when a glass panel
is broken in the door.

This Lock can be modified to use as a fire escape lock by removing the facility to lock the handle, this is then classified as a 3R35X.

The Chubb Lock can be keyed alike with other Detainer mortise lock, example a Chubb 3G110 or Chubb 3K70.

The latch is opened by key from either side and by lever handle from inside.

The lock is automatically dead latched when closed.

The 3R35 mortise dead locking latch is ideal for heavy traffic use where  security is needed.
