2-7/8” Wide Flat-Back Aluminum Hidden Shackle

2173A hockey puck-style padlock offers superior security; is precision CNC machined in the USA for quality and dependability; and comes standard with a 6-pin bump and pick resistant rekeyable cylinder. The 2173A has a flat-back to fit shrouded Hasps and tapped holes specifically designed to fit PL770, PL775, and PL801S 1/4” steel Hasps — this allows the lock to stay connected to the HASP when opened.

The solid body 2173A is machined from 6061 aircraft-grade aluminum, anodized in one of ten available colors, and resistant to corrosive environments. The 2173A’s hidden shackle design protects your lock from direct access by bolt cutters and hacksaws. With only one moving part, the 2173A lacks the environmental vulnerabilities that traditional, shackled padlocks have. Even after years of exposure to the elements, this lock will still function.
