The Medeco® Maxum deadbolt exceeds Grade 1 ANSI/BHMA A156.36 standard for auxiliary locks. Solid brass, free turning collar and 1/4 inch diameter mounting bolts resist wrenching, prying and hammering attacks. One inch throw hardened steel bolt resists sawing and crowbar attacks.
Hardened steel inserts and rotating pins provide drill and pick resistance in accordance with UL437 standard for safety for key locks. The Medeco3 design offers a utility patent that provides protection against unauthorized key duplication.
