Medeco M3 11TR503-605 Bright Brass Deadbolt

The Medeco M3 11TR503-605 Deadbolt is about strength. Just hold a Medeco® ANSI Grade 1 Maxum® deadbolt in your hand, and you know this is one tough hunk of protection. As tough as a Maxum® deadbolt is on the outside, it’s that smart on the inside. It features the triple-locking security of a Medeco3 cylinder.

Designed with a residential aesthetic, the Maxum® Residential Deadbolt is available as a single- or double-cylinder or with a unique “captive thumbturn.” The captive thumbturn converts the inside cylinder to a thumbturn for safe exit when the facility is occupied. A quick conversion when the facility is not occupied returns it to double cylinder mode and guards against unauthorized entry or exit. Maxum® deadbolts offer maximum protection with solid-brass construction, along with anti-drilling and anti-prying features.

Key Duplication: is authorized with Medeco card supplied with lock. Restriction is straight forward “No Card No Keys”.
2 keys are included with lock, any additional keys will need card present at any authorized locksmith Medeco dealer to duplicate keys.
