EZDCC108SS Double Chain Clamp 10" - 108" Stainless Steel

Mathey Dearman EZDCC108SS Double Chain Clamp is an extra 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 contact points and chain 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 of pipes and vessels up to 20 ft (6 m) long with Schedule 80 wall thickness, handling out-of-round conditions while keeping all areas accessible for welding.
