Medeco MED-11C631T-05-DLT – Frequently Asked Questions

1) What is the grade rating and security level of the Medeco Maxum commercial deadbolt?
The Medeco Maxum is Grade 1 ANSI/BHMA certified for commercial applications. Features patented rotating tumbler technology and drill-resistant construction for high security environments.
2) What door thickness and preparation does this deadbolt require?
Fits standard 1-3/8" to 1-3/4" door thickness with 2-1/8" cross bore and 1" edge bore. Uses ANSI A115.2 Series 4000 template. Verify door thickness before ordering.
3) How does the double cylinder configuration work?
Double cylinder requires key operation from both sides. No thumb turn on interior. Provides maximum security by preventing unlocking from inside without proper key.
4) What does "captive key" mean on this deadbolt?
Captive key feature prevents key removal when bolt is extended. Key remains in cylinder until deadbolt is unlocked. Ensures door cannot be left unlocked with key removed.
5) What is the DL keyway and can it be master keyed?
DL is a Medeco restricted keyway requiring authorization to duplicate keys. Can be master keyed within Medeco systems. Contact locksmith for master key arrangements and key control options.
6) What backset options are available for installation?
Standard 2-3/8" backset with optional 2-3/4" available. Measure from door edge to center of existing bore hole to determine required backset before installation.
7) Can this deadbolt be used on fire-rated doors?
Check fire door manufacturer specifications and local fire codes. Many commercial applications require specific fire-rated hardware. Consult AHJ for compliance requirements.
8) What finish options does the Maxum series offer?
Available in multiple commercial finishes including satin chrome, oil rubbed bronze, and bright brass. Verify specific finish availability for this model configuration.
9) How do I adjust the bolt throw length?
Standard 1" throw length is factory set. Bolt extension is not field adjustable. Ensure strike box and frame preparation accommodate full 1" throw for proper security.
10) What maintenance does the Medeco Maxum require?
Lubricate cylinder and bolt mechanism quarterly with graphite or approved lock lubricant. Avoid oil-based products. Check bolt alignment and strike adjustment during routine maintenance.
11) Can I rekey this deadbolt to match existing keys?
Requires authorized Medeco locksmith due to restricted keyway. Cannot be rekeyed with standard tools. Medeco rotating tumblers require specific equipment and authorization.
12) Are replacement parts available for the Maxum series?
Yes, cylinders, strike plates, and hardware components available through authorized dealers. Browse our Medeco products section for compatible parts and accessories.
