Medeco 11R50W Maxum Single Cylinder Deadbolt — Biaxial, G3 Keyway, UL 437 High-Security

The Medeco 11R50W Maxum Single Cylinder Deadbolt delivers benchmark residential security through advanced Biaxial technology and the G3 Keyway system, combining physical durability with superior key control. Engineered with hardened steel inserts, rotating pins, and a solid 1" hardened steel bolt housed in heavy-gauge steel, this deadbolt resists picking, drilling, bumping, wrenching, and kicking in full compliance with UL 437 standards. Designed to fit doors 1-3/8" to 2-1/2" thick with a standard 2-1/8" crossbore and 1" edge bore (ANSI A115.13 prep), the Maxum integrates seamlessly into new and existing residential door preparations. It can be master keyed into Medeco M4, M4 BiLevel, and M4 CLIQ systems for expanded key management flexibility.

The Biaxial G3 keyway provides enhanced pick resistance through angled cuts and dual-axis key engagement. Keys cannot be duplicated without proper authorization. Offers superior security over conventional pin tumbler systems.

6) Can I rekey this deadbolt to match existing Medeco keys?

Use graphite lubricant only - never oil-based products. Insert key fully and turn smoothly. Clean exterior with mild soap solution. Avoid forcing keys or over-turning mechanism.

Medeco offers coordinating residential hardware in matching finishes. Look for Maxum series entry sets and handlesets. Door hardware sections show compatible options.
