EZDCC54SS Double Chain Clamp 10" - 54" Stainless Steel

Mathey Dearman EZDCC54SS Double Chain Clamp (D236SS) 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 nickel-plated carbon steel duplex roller chain with stainless steel jackscrews, jackbars, and main block. It ensures accurate alignment and reforming for pipes up to Schedule 80 from 10" to 54" (254 mm to 1372 mm) up to 20 ft (6 m) long, handling elbows, tees, flanges, end caps, and fittings while keeping all areas accessible for welding.
