Medeco 5262 Brass Body Padlock with 5/16" Shackle Diameter and M3 Key Technology
The Medeco 52 Series Brass Body Padlock is engineered for demanding commercial security applications, featuring a 5/16" shackle diameter and Medeco M3 key technology for superior access control. The padlock case is constructed of brass with a Satin Chrome (26) finish, and shackle options include stainless steel for corrosion protection or hardened boron alloy steel for resistance against cutting, sawing, and prying. Designed to be keyed with Medeco's 60 Series cam locks and switch locks, this padlock accepts UL listed cylinders and cores that are virtually pickproof and drillproof, making it ideal for indoor and outdoor applications ranging from industrial safekeeping to perimeter gates and cargo vehicles.
Key Features
- 5/16" Shackle Diameter: Available in stainless steel for corrosion protection or hardened boron alloy steel for strong resistance against cutting, sawing, and prying attacks.
- Brass Padlock Body: Durable brass case construction with Satin Chrome (26) finish provides long-lasting performance in both indoor and outdoor environments.
- Patented Key Control: M3 key technology protects against unauthorized key duplication, requiring a special key cutting machine and access to Medeco-specific blanks available in a variety of restriction levels.
- UL Listed Cylinders & Cores: Accepts cylinders and cores that are UL listed and virtually pickproof and drillproof, with mechanical cylinders providing resistance to physical attacks.
- Picking and Bumping Protection: M4 cylinders utilize cylinder side pins, a lift pin, and a movable key element to engage a sidebar, preventing key rotation until elements are correctly rotated and aligned — protecting against bumping, picking, and other attacks.
- Toe and Heel Deadbolt Locking Action: Dual-point locking mechanism provides enhanced security and resistance to forced entry.
- 60 Series Compatibility: Designed to be keyed with Medeco's 60 Series cam locks and switch locks for integrated master key system flexibility.

- Flexible Keying Options: Available keyed differently, keyed alike, or master keyed; offered in non-key retained or key retained functions to suit specific operational needs.
- Optional Dust Cover: Protects the keyway of the cylinder from weather conditions, extending service life in outdoor or harsh environments.
