Grade 1 deadbolt for commercial

The Medeco Maxum 11-R504-619-00 is a single-cylinder tubular deadbolt built to ANSI/BHMA A156.30 Grade 1 standards with UL437 listed cylinders. It fits doors from 1-3/8" to 2-1/2" thick and uses a 2-3/4" backset with a 1" faceplate. The solid-brass construction includes anti-drilling and anti-prying features for high-security applications.

Installation requires standard 2-1/8" crossbore

This lock installs into a standard 2-1/8" crossbore and a 1" edge bore. The tubular mechanism accepts the Original 00 keyway with a 5-pin tumbler cylinder providing triple locking security against picking and key duplication. Satin Nickel US15 finish suits residential aesthetics while meeting commercial durability requirements. Not suitable for doors thinner than 1-3/8" or thicker than 2-1/2", or for installations needing a double-cylinder or electronic operation.

Original 00 keyway with 5-pin tumbler cylinder

The lock uses Medeco's Original 00 keyway with a 5-pin tumbler cylinder that delivers pick resistance and controlled key duplication. This specific keyway determines whether existing keys or master-key systems will be compatible. Buyers needing a different keyway, a 6-pin cylinder, or compatibility with an existing Medeco BiLevel or Medeco3 system cannot use this cylinder.

Questions about this item

Should I choose the 2-3/4" backset or a different size for my door?

Select the 2-3/4" backset when your existing bore hole measures that distance from the door edge; the 1" faceplate and 1" edge bore must also match your current cutout.

What does the Grade 1 rating mean for daily security?

Grade 1 indicates the highest ANSI/BHMA A156.30 residential grade, confirming the deadbolt meets stringent cycle, impact and forced-entry tests for heavy-duty use.

How does the Original 00 keyway affect key control?

The Medeco Original 00 keyway uses a 5-pin tumbler with UL437-listed cylinder, providing patented key control that resists picking and unauthorised duplication.
