Steel Drag Chain
Strong simple chains consisting of barrels welded to the link plates.
These chains are heavy and the links are flared at the lower end enabling
them to move any material, no matter how hard or heavy. Barrels are arranged
perpendicularly for maximum moving effectiveness and also to prevent the
chain from riding up over the material.
