The Mathey Dearman Double Chain Clamp is a heavy-duty vessel clamp designed for alignment and reforming of pipes and vessels up to 20’ (6 m) in diameter with Schedule 80 wall thickness. Our Double Chain Clamps also align Schedule 80 pipe and heavier when no reforming is required. The extra heavy-duty Jackbars and Main Block provide the brute strength necessary to accomplish even the toughest reforming jobs. Models 10” to 36” through 10” to 54” come with a Level and Support Device. All other models come with a cable hoist. The Double Chain Clamp is available in steel and stainless steel versions and is shipped in a wooden crate.
