Model 400-IC2


2-7/8” Wide 1/4” Hardened Steel Stepped-Back Hidden Shackle SFIC Padlock




PACLOCK’s 400-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 400-IC2 has a stepped-back cut-out to fit bar-style Hasps. The solid body 400-IC2 is machined from hardened steel, electroless nickel plated for extreme toughness, and resistant to the environment.

The 400-IC2’s hidden shackle design protects your lock from direct access by bolt cutters and hacksaws. With only one moving part, the 400-IC2 lacks the environmental vulnerabilities that traditional, shackled padlocks have. Even after years of exposure to the elements, this lock will still function.
