Master Lock 6850LJ Pro Series Brass Padlock Keyed Different

Product Description

The MASTER LOCK 6850LJ is a Pro Series brass padlock designed for security applications where corrosion resistance and durability are required. The body is solid brass measuring 2 inches wide and 2-11/32 inches high. The shackle is boron alloy, a hardened steel-alloy material that resists cutting and sawing. A 5-pin tumbler cylinder provides pick resistance suited to commercial and industrial use. At 0.96 pounds, this padlock is a solid, full-size unit intended for installation by maintenance technicians, facilities staff, locksmiths, and security contractors.

This padlock is appropriate for securing gates, hasps, chains, storage units, equipment enclosures, and outdoor fixtures in both residential and light commercial environments. The brass body handles moisture exposure well, making it a common choice for outdoor and marine-adjacent applications. Each unit is keyed different, meaning no two locks in a purchase share the same key bitting — standard for applications requiring individual key control across multiple lock points.

Compatibility

Designed as an OEM-style replacement or direct-fit padlock for standard hasp, chain, and gate locking applications requiring a 3/8-inch shackle diameter and 2-inch body width.

Installation Notes

Installation requires no special tools beyond a compatible hasp or chain rated for the shackle diameter of 3/8 inches. Verify the hasp staple opening accommodates the 29/32-inch shackle width before installation. Do not force the shackle closed if the hasp staple is misaligned, as this can damage the locking mechanism. Key control records should be maintained when deploying keyed-different locks across multiple points.
