EZDCC84SS Double Chain Clamp 10" - 84" Stainless Steel

Mathey Dearman EZDCC84SS Double Chain Clamp (D251-1084SS) is a heavy-duty alignment and reforming tool designed for precise pipe fit-up in welding, fabrication, and industrial piping applications. This stainless steel version features corrosion-resistant stainless steel chain and contact points to enable contamination-free welding of exotic materials, constructed from robust heavy-duty steel with independent pivoting jackscrew pads. It ensures accurate alignment and reforming for Schedule 80 pipes from 10" to 84" (254 mm to 2134 mm) up to 20 ft (6 m) long, handling elbows, tees, flanges, end caps, and fittings while keeping all areas accessible for welding.
