Medeco Maxum Grade 1 Deadbolt

The Medeco Maxum 11-R604-605-00 is a Grade 1 single-cylinder tubular deadbolt built for commercial and heavy-duty residential doors. It uses the high-security Original 00 keyway with a six-pin tumbler cylinder that resists picking and unauthorised key duplication. The bright brass finish suits apartments, retail outlets and multi-family units where consistent quality is required.

Solid Brass Construction and Standard Mounting

Solid brass components deliver anti-drill and anti-pry protection while meeting ANSI/BHMA A156.30 and UL 437 cylinder listings. The 2-3/4 inch backset and 1 inch faceplate fit standard door preparations with a 2-1/8 inch crossbore and 1 inch edge bore. Installation covers door thicknesses from 1-3/8 to 2-1/2 inches without modification.

Mechanical Operation Without Power Draw

As a purely mechanical deadbolt it draws no electricity and produces no fan or motor noise during use. The cylinder turns smoothly on the six-pin tumbler mechanism, and the bolt throws positively into the strike. There are no thermal considerations, making it suitable for any interior or exterior door where reliable, maintenance-free locking is needed.

Questions about this item

What ANSI/BHMA grade does the 11-R604-605-00 meet and what security level does that indicate?

It meets Grade 1 under ANSI/BHMA A156.30, the highest residential and commercial rating for strength and cycle life.

What door thickness range and bore sizes are required to mount this deadbolt?

The lock fits doors 1-3/8" to 2-1/2" thick and needs a 2-1/8" crossbore with a 1" edge bore.

How is the Medeco Original 00 keyway cylinder installed and what common step is missed?

Insert the cylinder into the housing, secure the retaining screw, then test both thumbturn and key; installers often forget to tighten the set screw that locks the cylinder in place.
