The J lever design offers a comfortable, grip, and the mortise lock body delivers the durability demanded by institutional, healthcare, and educational facilities.

Functional Details
This 24V DC electrified ET trim operates in fail safe mode. With power removed, the outside lever is unlocked. Applying power locks the outside lever. When unlocked, turning the outside lever retracts the mortise latch. Operating the inside push rail permits egress regardless of the electrical state of the trim. A compatible mortise cylinder, ordered separately, provides mechanical key override.
Trim and Lever Details
The ET trim has a J lever. Electrical power controls whether the outside lever is locked or unlocked; operating an unlocked lever retracts the latch. Select the LHR or RHR handing to suit the opening.
Included Components
Device ships as a complete mortise exit device with electrified ETJ trim and J lever. A compatible mortise cylinder must be ordered separately, as this model is supplied less cylinder.
