Model 2173-IC2


2-7/8” Wide Hardened Steel Flat-Back Hidden Shackle SFIC Padlock – w/ Mounting Holes for American Lock®’s A801 Hasp & PACLOCK’s PL770 & PL775 Hasps




PACLOCK’s 2173-IC2 SFIC hockey puck-style padlock offers superior security; is precision CNC machined in the USA for quality and dependability; and works with your 5, 6, and 7 pin small format interchangeable cores. The 2173-IC2 has a flat-back to fit shrouded Hasps and tapped holes specifically designed to fit American Lock®’s A801 HASP and PACLOCK’s PL770 and PL775 1/4” steel Hasps — this allows the lock to stay connected to the HASP when opened.

The solid body 2173-IC2 is machined from hardened steel, electroless nickel plated for extreme toughness, and resistant to the environment. The 2173-IC2’s hidden shackle design protects your lock from direct access by bolt cutters and hacksaws. With only one moving part, the 2173-IC2 lacks the environmental vulnerabilities that traditional, shackled padlocks have. Even after years of exposure to the elements, this lock will still function.
