Medeco Maxum Double Cylinder Deadbolt

The Medeco Maxum 11-C621-605-00 is a Grade 1 tubular deadlock built for exterior doors. Its solid brass construction and bright brass finish deliver high-security protection for homes and commercial premises. The lock carries ANSI/BHMA A156.36 Grade 1 and UL437 certifications. It operates with an Original 00 keyway.

Double Cylinder Keyed Both Sides

This deadbolt requires a key to lock or unlock from either the interior or exterior. That single specification determines whether the lock matches your egress requirements and local fire codes. The 2-3/8 inch backset and 1-1/8 inch faceplate suit standard door preparations.

Commercial and Heavy-Duty Residential Fit

The deadlock suits offices, schools, hospitals, retail outlets and apartment buildings where consistent quality is specified. It fits doors 1-3/8 to 2-1/2 inches thick. Buyers who need a single-cylinder function for easier interior exit should look at a different configuration.
