Best 21B722L Brass Padlock 7 Pin 1-1/2 Inch Shackle

Product Description

The BEST 21B722L is a brass padlock designed for commercial and institutional access control applications where corrosion resistance and key control are required. The lock features a 7-pin cylinder for increased pick resistance and a 1-1/2 inch shackle clearance with a 5/16 inch shackle diameter. Brass construction resists oxidation in outdoor or high-humidity environments. This padlock is sold as a single unit and is intended for installation by licensed locksmiths or facility security technicians managing keyed-alike or master key systems.

The 21B722L fits applications where durable, high-security padlocks are specified on gates, hasps, equipment enclosures, and utility access points in commercial, industrial, and institutional settings. The 7-pin configuration supports BEST interchangeable core and master key system integration, making it suitable for large facilities requiring hierarchical key access across multiple points. Non-key-retained shackle operation is standard on this model.

Installation Notes

Installation and keying should be performed by a licensed locksmith or credentialed security technician familiar with BEST master key systems. Ensure the hasp, staple, or anchor point is rated to match the shackle diameter and load requirements before installation. Follow applicable local building and security codes when specifying padlocks on life-safety or restricted-access openings. Do not force the shackle or attempt to modify the cylinder without proper tooling and authorization.
