Wide variations to protect workers who
enter hazardous areas.
• Models with Trapped Keys (mechanical lock models only)
As long as a person has the trapped key when he enters a
hazardous area, he does not have to worry about somebody
locking the door and trapping him inside.
The door can be opened only by supplying power to the solenoid
and then turning the trapped key to unlock the D4JL.
There are thirty different types of trapped keys available for use in
applications with adjacent hazardous areas.
• Models with Rear Release Buttons
A rear release button allows the door to be unlocked from inside a
hazardous area in an emergency.

The padlock that can be attached to the disable-prevention cover
prevents other workers from restarting machines.
