The Adams Rite 8800EL Exit Device is the Electric Latch Retraction version of the 8800.  We see this used with many card readers, especially in Hotel/Motel applications.

The 8800 features the Starwheel locking bolt that interlocks door to the door frame.  This device is used exclusively on aluminum framed glass storefront doors.  If your door is 35" wide, then you would order the 36" device.  We want to make sure they device is wide enough to span the glass on the storefront doors.  Replacement parts are available.

To order specify your door width, color and voltage of the solenoid.
