Medeco Grade 1 Double Cylinder

The Medeco 11-C622-605-00 is a Grade 1 double cylinder tubular deadbolt built for high-security residential and commercial doors. It features solid brass construction, a bright brass 605 finish, and the original 00 keyway. The lock meets ANSI/BHMA A156.36 Grade 1 standards and carries a UL437 listing for cylinder security.

Suits exterior doors needing keyed entry both sides

This deadbolt fits doors 1-3/8" to 2-1/2" thick with a 2-3/4" backset and 1-1/8" faceplate. It is designed for offices, schools, hospitals, and heavy-duty residential use where key control is required. Buyers needing a single-cylinder function or a different backset dimension should look at other models.

Solid brass resists sustained attack

The solid brass body and UL437 cylinder provide continuous resistance to drilling and prying during prolonged forced-entry attempts. Grade 1 certification confirms the lock withstands heavy-duty cycling and abuse over time. The double cylinder design maintains security on both faces without degradation.
