11R523 M3 Medeco Maxum Residential Double Cylinder Deadbolt
Beautiful solid brass hardware for discriminating tastes.
Double Cylinder requires a key on both the inside and outside to lock and unlock the door. This lock is best suited for doors that have glass panes on or near the door. It prevents an intruder from breaking the glass and reaching in to unlock the door. Recommended for use on businesses to secure doors after hours when the building is unoccupied. Extreme caution should be used when installing double cylinder locks on homes or apartments. Always check local building codes and make provisions to have a key hanging nearby or have at least one other door that does not require a key to exit. You should also consider using Medeco's captive thumbturn deadbolt.
Exceeds ANSI Grade 1 standard for auxiliary locks. Solid brass, free turning collar and 1/4 inch diameter mounting bolts resist wrenching, prying and hammering attacks. 1 inch throw hardened steel bolt resists sawing and crowbar attacks. Hardened steel inserts and rotating pins provide drill and pick resistance according to UL 437 standard. The Medeco3® design offers a utility patent that provides protection against unauthorized key duplication.
