Medeco Maxum Residential Deadbolt M3 6-Pin Captive Key DL Keyway — UL 437 Listed & BHMA Grade 1 Certified
The Medeco Maxum Residential Deadbolt is a UL 437 Listed, BHMA A156.5 Grade 1 Certified high-security deadbolt engineered to deliver unmatched protection against unauthorized key duplication, bumping attacks, picking, drilling, wrenching, kicking, and other forms of physical abuse. Featuring a solid 1" hardened steel bolt housed in a heavy-gauge tubular steel body, the Maxum fits doors 1 3/8" to 2 1/2" thick and installs into a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep). The M3 6-pin cylinder with DL Keyway and captive key technology is backed by ANSI/BHMA A156.36 Grade 1 and UL 437 listed cylinder ratings, making it one of the most secure residential deadbolts available.
Key Features
- UL 437 Listed & BHMA A156.5 Grade 1 Certified: Meets the highest residential deadbolt standards for resistance to picking, drilling, and physical attack.
- Solid 1" Hardened Steel Bolt: Heavy-gauge tubular steel housing surrounds the bolt and throwing mechanism for maximum resistance to crowbar and physical attacks.
- Door Thickness Compatibility: Fits doors 1 3/8" to 2 1/2" thick with a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep).
- Medeco 4 (M4) Key Control Technology: Patent-pending design with a movable element deters unauthorized key duplication and 3D-printed key copies, backed by BHMA A156.30 Certification.
- Special Angle Cut Keys: Requires a special key cutting machine and Medeco-specific blanks; angled cuts plus fore-and-aft positioning dramatically increase key combinations for large master key systems.
- Drill & Pick Resistance: Hardened steel inserts and rotating pins provide drill and pick resistance per UL 437; solid-brass construction with strategically placed drill pins offers maximum protection.
- Steel Shroud Over Bolt: Protects against "ice pick" type attacks for added physical security.
- High-Security Strike Plate: Special box design with 2" screws anchors the strike directly to the building structure behind the frame, preventing kick-in attacks.
- Master Keying Capabilities: Can be master keyed into systems including M4, M4 BiLevel, and M4 CLIQ keys and cylinders; supports extremely large master key systems.
- Available Finishes: Offered in 14 finishes including Bright Brass, Satin Brass, Antique Brass, Satin Brass Blackened, Bright Bronze, Satin Bronze, Oil Rubbed Bronze, Bright Nickel, Satin Nickel, Antique Nickel, Black, Dark Bronze, Bright Chrome, and Satin Chrome.
