Medeco Grade 1 Single Cylinder Deadbolt

This Medeco Maxum deadbolt provides Grade 1 security for commercial and heavy-duty residential doors. It uses a 6-pin tumbler cylinder with the Original 00 keyway to resist picking and unauthorised key duplication. Solid brass construction adds anti-drill and anti-pry protection. The satin nickel finish suits modern hardware styles.

Installation requires standard 2-1/8" crossbore

The lock fits doors between 1-3/8" and 2-1/2" thick with a 2-3/4" backset and 1" faceplate. Alignment of the crossbore and edge bore is critical; mis-drilled holes prevent the bolt from throwing fully. Verify door thickness and backset before drilling to avoid costly rework.

ANSI/BHMA A156.30 and UL 437 listed cylinder

These certifications confirm the cylinder meets the highest residential and commercial security standards for physical attack resistance. Buyers needing a lower backset, double-cylinder function, or a different keyway cannot use this model.

Questions about this item

How can I confirm the Medeco 11-R604-619-00 deadbolt is working correctly after installation?

Turn the interior thumbturn and the exterior key; the bolt should extend smoothly into the 2-1/8" crossbore and retract without binding, and the key should rotate cleanly in the Original 00 keyway.

What components are included with the Medeco 11-R604-619-00 and what must I purchase separately?

The box contains the single-cylinder tubular deadbolt with satin nickel finish, 2-3/4" backset, 1" faceplate, and two keys for the Original 00 keyway; you must supply mounting screws and a strike plate separately.

Which Medeco Maxum version should I choose for a door that is 1-3/4" thick with a standard 2-1/8" crossbore?

This 11-R604-619-00 model fits doors 1-3/8" to 2-1/2" thick and matches a 2-1/8" crossbore, making it the correct Grade 1 single-cylinder deadbolt for that door.
