Grade 1 Deadbolt for Commercial
The Medeco Maxum 11-R633-619-00 is a Satin Nickel tubular deadbolt built to ANSI/BHMA A156.30 and UL 437 standards. Its six-pin captive key cylinder provides triple locking resistance against picking and unauthorised key duplication. Solid brass construction adds anti-drill and anti-pry protection for high-security needs.
Captive Thumbturn Converts Between Double
Unlike fixed double-cylinder deadbolts, the captive thumbturn lets occupants switch to thumbturn operation for safe egress when the building is occupied. Reverting to double-cylinder mode secures the door against unauthorised entry or exit when the premises are empty. This flexibility removes the need to choose one mode at purchase.
Fits Standard Door Preps From 1-3/8" to 2-1/2" Thick
The lock installs into a 2-1/8" crossbore with a 1" edge bore and a 2-3/8" backset using the included 1" faceplate. It accommodates door thicknesses ranging from 1-3/8" to 2-1/2" without additional parts. The Original 00 keyway integrates with existing Medeco master-key systems where specified.

Questions about this item
What door thickness and bore sizes does the 11-R633-619-00 deadbolt require?
It 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 captive thumbturn converted between thumbturn and double-cylinder modes on this Medeco Maxum lock?
The inside cylinder rotates to become a thumbturn for occupied use; reversing the action restores double-cylinder operation when the facility is empty.
When should the 6-pin Original 00 keyway cylinder be rekeyed or replaced on this Grade 1 deadbolt?
Rekey the 6-pin cylinder if keys are lost or access changes; replace it only if the mechanism shows wear or after a forced-entry attempt.
