Medeco Grade 1 Single Cylinder Deadbolt

The Medeco 11-R504-605-00 is a Grade 1 single cylinder tubular deadbolt finished in bright brass. It uses a 5-pin tumbler cylinder with the Original 00 keyway to deliver triple locking security against picking and unauthorised key duplication. Solid brass construction adds anti-drilling and anti-prying resistance for commercial and heavy-duty residential doors.

Sustained Physical Attack Resistance

ANSI/BHMA A156.30 and UL 437 listed cylinders maintain their protective performance during prolonged attack attempts. The solid brass body and hardened internal components resist drilling, prying and forced entry without degradation over time. This deadbolt is built for apartments, retail outlets and multi-family units where consistent high security is required daily.

Door Preparation Checklist

Verify the door thickness falls between 1-3/8" and 2-1/2" before ordering. Confirm the existing crossbore measures 2-1/8" and the edge bore is 1" to match the deadbolt dimensions. Ensure the backset is 2-3/4" and the faceplate width is 1" for correct alignment and installation.

Questions about this item

Does the Medeco 11-R504-605-00 deadbolt generate any noise or heat during continuous daily operation?

No, the mechanical single-cylinder deadbolt has no motor or electronics, so it produces no audible noise and no heat when locked or unlocked repeatedly throughout the day.

What door preparation must already exist for the 2-3/4" backset and 1" faceplate to install correctly?

The door needs a 2-1/8" crossbore, a 1" edge bore, and a thickness between 1-3/8" and 2-1/2" to match the factory specifications.

Will the Original 00 keyway work with the Medeco keys I already use on other locks in the building?

Yes, if your existing Medeco cylinders are also cut to the Original 00 keyway, the same keys will operate this Grade 1 deadbolt alongside them.
