Medeco Grade 1 Deadbolt with Captive Cylinder

The Medeco Maxum 11-R534-619-00 is a Grade 1 tubular deadbolt built for high-security residential and commercial doors. It features a 5 pin tumbler cylinder with the Original 00 Keyway and a satin nickel finish. The captive thumbturn converts between double-cylinder and thumbturn operation for flexible egress control. This lock suits owners needing certified physical attack resistance.

Fits Standard Door Preps with 2-3/4 Inch Backset

Installation requires a 2-1/8 inch crossbore and a 1 inch edge bore on doors 1-3/8 to 2-1/2 inches thick. The 1 inch faceplate mounts to the door edge. Solid brass construction integrates anti-drilling and anti-prying features directly into the lock body. The captive cylinder design frees the interior from a permanent key requirement when converted to thumbturn mode.

ANSI BHMA A156.30 and UL 437 Certified Hardware

The cylinder meets UL 437 listing and ANSI BHMA A156.30 Grade 1 standards for high-security mechanical locks. Solid brass components resist physical attack without electronic parts that consume power. Operation is purely mechanical, producing only the sound of the bolt throw and key rotation. No batteries or wiring are needed for the locking mechanism to function.

Questions about this item

How does the Grade 1 rating hold up under repeated forced-entry attempts?

The lock meets ANSI/BHMA A156.30 Grade 1 requirements and is UL 437 listed, certifying resistance to drilling, prying and picking during sustained attack.

Does the solid-brass construction or the captive thumbturn generate noticeable heat or noise during all-day operation?

Mechanical deadbolts have no motor or electronics, so they produce no heat and only the audible click of the bolt throwing or retracting.

What door preparation must already exist for this deadbolt to install without new drilling?

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 2-3/4" backset and 1" faceplate.
