Installation Notes

This key is used by locksmiths, door hardware technicians, and qualified service professionals working on panic exit hardware in commercial facilities. Before servicing an exit device, ensure the door is secured and traffic flow through the opening is controlled. Consult the exit device manufacturer documentation and applicable building and fire codes, including NFPA 101, before dogging any life-safety exit device. Do not use substitute hex keys of approximate size, as improper tools can damage the dogging mechanism.
