Securitech Trident Multi-Point Deadbolt Exit Lock

Trident 4-point deadlocking exit device.

Simple and robust design helps to ensure security and longevity; single motion egress ensures life safety code compliance.  

Simple to order and to install, the Trident offers excellent security while preserving life safety.

The first thing I noticed when I unpacked the box was the small number of parts.  The second thing I noticed was how well all of these parts are labelled.  As I read the installation instructions I was struck by how easy Securitech had made the installation process, especially with the inclusion of a metal template to help get everything lined up just right.

I assume that the Trident is named for the three active bolts that secure the door on the lock side, but with the inclusion of the passive hinge side bolt it is actually a four point lock.  The hinge side bolt slides passively into its keeper whenever the door is closed.

Trident is a heavy device, so before installing it, make sure your door swings and closes properly and the hinges are in good shape.  I suggest using hinges with non-removeable pins so as not to rely solely upon the Trident’s hinge side bolt.  A stainless steel continuous hinge would be even better for both security and durability, if it is possible to use one.

Every locking mechanism of the Trident is through-bolted through pry-resistant steel plates, so casual attack using a pry bar would likely be fruitless no matter how much time the would-be burglar might have.  Each locking bolt is substantial and housed in a very sturdy mechanism.  Bending one of them would be difficult; bending all of them enough to gain entry would be almost impossible.  The main outside plate is impressive-looking with its Securitech logo and satin stainless steel finish, and since it is through-bolted to the head of the device in several

places, it’s pretty strong, too.

The weakest part of any muli-point locking device is the door frame.  Fully grouted (concrete filled) hollow metal frames hold up the best under attack.  At the very least, to have real security measures must be taken to ensure that the door frame cannot be either pulled out of the wall or bent away from the locking bolts.

To maximize security, I suggest not using the optional exterior key control with this device.  The presence of a key cylinder outside provides a target for burglars.

The Trident comes standard with a paddle that tells the user to push to exit and alarm will sound, but since the alarm is optional, this may be an empty threat.  Be sure to order your Trident with an alarm if you want one.

I was impressed with the workmanship evident in how the Trident is put together.  Everything worked super-smoothly and fit together perfectly.  The strong, simple design looks like it will provide many years of flawless service.  I highly recommend it for the back doors of stores, warehouses or factories or anywhere where a higher level of security may be needed.
