Medeco Maxum 11C61W Commercial Single Cylinder Deadbolt — Biaxial, G3 Keyway, Classroom Function

The Medeco Maxum 11C61W is a heavy-duty, ANSI/BHMA A156.36 Grade 1 single cylinder deadbolt engineered for demanding commercial applications where high-security key control and physical attack resistance are paramount. Built with solid-brass construction and UL 437 listed cylinders, this 6-pinned Biaxial deadbolt 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 G3 Keyway and Classroom Function configuration make it an ideal choice for educational facilities and other environments requiring controlled access with reliable egress.

Key Features

• Door Thickness Compatibility: Fits doors 1 3/8" to 2 1/2" thick, accommodating a wide range of commercial door constructions.
• Standard Door Prep: Designed for a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep) for straightforward installation.
• Solid-Brass Construction: Heavy-duty solid-brass body provides exceptional resistance to drilling, prying, and physical attack for long-term commercial reliability.
• UL 437 Listed High-Security Cylinders: ANSI/BHMA A156.36 Grade 1 and UL 437 listed cylinders deliver maximum protection against picking, bumping, and other forms of physical attack.
• Biaxial Key Control (M4 Technology): Patent-pending key control protects against unauthorized key duplication; M4 cylinders use cylinder side pins, a shuttle lift pin, and a movable key element to engage a sidebar, preventing the key from turning until elements are rotated and aligned correctly — guarding against bumping and picking.
• Protection Against 3D Printing: A patent-pending movable element in the key deters unauthorized 3D printed copies of keys or blanks, providing a modern layer of security.
• Special Angle Cut Keys: Requires a special key cutting machine and access to Medeco-specific blanks, available in a variety of restrictions to support every security need.
• Master Keying Capabilities: M4 deadbolts can be master keyed into a system that includes M4, M4 BiLevel, and M4 CLIQ keys and cylinders, supporting extremely large keying systems.
• Classroom Function: Cylinder x Thumbturn product function supports classroom-style operation for controlled access in educational and institutional environments.
