Medeco MED-11C601T-26-DLT – Frequently Asked Questions
1) What is the Medeco Maxum Commercial Single Cylinder Deadbolt designed for?
This deadbolt provides high-security protection for commercial applications. Features restricted key control and drill-resistant construction. Suitable for office buildings, retail spaces, and institutional facilities requiring Grade 1 security.
2) What door thicknesses does this deadbolt accommodate?
Standard adjustable backset fits doors from 1-3/8" to 1-3/4" thick. Extended versions available for thicker commercial doors. Verify your door thickness before ordering to ensure proper fit.
3) How do I determine the correct handing for installation?
Stand on the side where the door opens away from you. If hinges are on your right, it's right-handed. If hinges are on your left, it's left-handed. Most single cylinder deadbolts are non-handed and work for both swing directions.
4) What is the DL keyway specification?
DL keyway is a restricted Medeco keyway requiring authorized dealer verification. Provides enhanced key control and prevents unauthorized key duplication. Contact your Medeco dealer for key cutting and additional cylinders.
5) What security grade does this deadbolt meet?
Meets ANSI/BHMA Grade 1 commercial standards for strength and durability. Features hardened steel bolt and anti-drill plates. Tested for 800,000+ cycles and high torque resistance for demanding commercial use.
6) Can this deadbolt be keyed alike with existing Medeco locks?
Yes, if your existing locks use compatible Medeco keyways. Provide your key code or existing cylinder to your Medeco dealer for keying alike service. Restricted keyways require proper authorization.
7) What tools are needed for installation?
Requires 2-1/8" hole saw for cylinder, 1" spade bit for bolt, and standard drill bits for mounting screws. Use door lock installation kit with proper templates. Follow manufacturer's template for precise hole placement.
8) How do I adjust the bolt throw if needed?
Standard throw is 1" and typically requires no adjustment. If bolt binds or doesn't fully extend, check door alignment and strike plate positioning. Ensure proper door gap and frame square before adjusting hardware.
9) What finish options are available for this model?
Available in standard commercial finishes including satin chrome, bright brass, and oil-rubbed bronze. Verify finish availability for your specific model number. Match existing hardware finishes for consistent appearance.
10) Are replacement parts available for this deadbolt?
Yes, cylinders, thumbturns, and mounting hardware are available as service parts. Contact Medeco dealers for genuine replacement components. Keep model and serial numbers for accurate parts ordering.
11) What similar Medeco models should I consider?
Consider Medeco Maxum double cylinder for doors with glass panels. Maxim series offers similar security in different configurations. Browse our Medeco collection for compatible high-security options.
12) How does weather affect outdoor installation performance?
Designed for interior commercial use primarily. For exterior applications, ensure proper door overhang and weatherstripping. Apply graphite lubricant seasonally in harsh climates. Consider weather-resistant finishes for coastal or high-moisture environments.
