The electric mortise lock is electronically controlled. A mortise lock is a mechanism that sits inside the door. Wiring electricity into the mechanical system uses an electrical impulse from the wiring to stick out a bolt into the door frame to lock the door. When the power is off, the clip will retract, and unlock the door.
LBB-1, LBB-2, and UBB-1 are accessories that help install electric mortise locks, namely, LB12, LB22, and LB35, on glass doors.
