Grade 1 double-cylinder deadlock
The Medeco Maxum 11-R524-605-00 is a Grade 1 double-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 key duplication. Solid-brass construction adds anti-drilling and anti-prying resistance. The lock meets ANSI/BHMA A156.30 and UL437 listings for high-security applications.
Door-thickness range and backset
It fits doors from 1-3/8" to 2-1/2" thick with a 2-3/4" backset and a 1" faceplate. Installation requires a 2-1/8" crossbore and a 1" edge bore. The double-cylinder design requires a key on both sides, which restricts egress when locked from the inside and may not suit doors used as primary fire exits.
Mechanical operation and durability
The all-metal mechanism operates without electronic components, so there are no thermal, noise or power-draw considerations. Grade 1 certification confirms the lock withstands heavy-duty cycling and forced-entry tests in commercial and multi-family residential settings. Regular lubrication of the cylinder and bolt maintains smooth operation over the service life.

Questions about this item
Will this 2-3/4" backset deadlock line up with the existing bore holes on my older door?
The lock requires a 2-1/8" crossbore and a 1" edge bore; if your current door already has those dimensions the new deadlock will fit without new drilling.
How can I verify the Grade 1 rating and UL 437 listing are genuine once the lock is installed?
Look for the ANSI/BHMA A156.30 and UL 437 markings stamped on the cylinder face; those marks confirm the lock meets the certified standards.
Does the box include both interior and exterior cylinders plus the strike plate, or must I order the strike separately?
The double-cylinder assembly ships with both keyed cylinders and the matching strike plate in the same box, so no extra hardware is needed for a standard installation.
