Adams Rite 7100 Series Extension Lips

Adams Rite 7100 Series Electric Strikes Lip extensions are for center hung doors, thick doors, or other conditions that vary from the standard 44mm (1-3/4") thick door that closes flush (or near flush) with the jamb face. For existing 7100 Series Electric Strikes, a thin metal membrane in the standard lip can be drilled or punched out and the lip extension can be added in the field.
