Medeco 11C61 M3 Maxum Commercial Single Cylinder Deadbolt — 6-Pinned, DL Keyway, Classroom Function

The Medeco M3 Maxum Commercial Single Cylinder Deadbolt (Model 11C61) is a heavy-duty, high-security bored lockset engineered for maximum resistance against physical and covert attacks. Featuring ANSI/BHMA A156.36 Grade 1 certification and UL 437 listing, this 6-pinned deadbolt with DL Keyway and Classroom Function is built from solid brass construction with hardened steel components. It accommodates doors 1-3/8" to 2-1/2" thick, requires a standard 2-1/8" crossbore and 1" edge bore (ANSI A115.13), and is compatible with Medeco M3, M4, M4 BiLevel, and M4 CLIQ key systems for seamless master-keying integration.

Key Features

• Door Thickness Compatibility: Fits doors 1-3/8" to 2-1/2" thick, accommodating a wide range of commercial and residential door constructions.
• Standard Door Preparation: Requires a 2-1/8" crossbore and 1" edge bore per ANSI A115.13 for straightforward installation with common door prep.
• 1" Solid Steel Bolt: Features a 1" solid steel bolt with hardened steel shroud providing robust protection against ice-pick and crowbar attacks.
• Solid Brass Construction: Built with solid brass and hardened steel components to resist drilling, picking, bumping, and prying for long-term security performance.
• M3 Sidebar Mechanism: Medeco M3 technology utilizes sidebars and hardened inserts — the sidebar prevents key rotation until all elements are perfectly aligned, defeating bumping and picking techniques.
• Patented Key Control: Special angle-cut keys require proprietary key machines and blanks, preventing unauthorized duplication and reducing vulnerability to cloning and anti-3D printing attacks.
• Master Keying Capability: Compatible with M3, M4, M4 BiLevel, and M4 CLIQ key systems, enabling integration into existing Medeco master key hierarchies across platforms.
• Multiple Configuration Options: Available in single-cylinder, double-cylinder, and captive thumbturn configurations for tailored security and egress requirements.
