Folding Lock-Guard Box

For installations requiring fire-egress in case of an after-hours lock in, a Folding Lock Guard Box can be added to the Hooklock installation.  This allows the interior keyed cylinder to be replaced with a thumb-turn cylinder which can be operated by hand without the use of a key.  When the box is folded up and in-use, the thumb-turn cylinder can only be reached from the inside of the gate.  The box prevents someone on the outside from reaching through the gate and turning the lock while allowing someone on the inside to unlock the folding security gate without the use of a key.

When not in use, the Lock Guard Box folds down and collapses flat against the gate for storage.
