Installation Notes

Installation is performed by licensed locksmiths or qualified commercial door hardware technicians. Before servicing, disengage any access control power to the door and ensure the door is held open or properly blocked to prevent movement during work. Use the appropriate hex or socket driver to seat the thru bolt without overtightening, which can crack the escutcheon casting. Consult the L Series installation template and hardware prep drawings to confirm bolt placement matches the door preparation.
