The Crosby Group provides product users with “Red” U-Bolt Clips and forged Fist Grip Clips. Our wire rope clips meet the Federal Specification Number FF-C-450, considered the industry standard. Compared to cast iron clips, forged clips provide a greater rope bearing surface and have been proven to be more consistent in strength and durability. Whether wire rope forged clips perform efficiently or not depends on whether the manufacturing practices were done properly.
