Big Horn 11495 4″ x 10′ Clear-Flex Hose, boxed. Made of clear PVC, with a helix of heavy gauge wire, this quality hose is ideally suited for connecting machines to your dust collection system. This very flexible hose will make a 90 degree turn with only a 6″ radius, and unlike hoses made completely of plastic, the wire cord supporting this hose can be grounded to the machine for dissipation of static charges.
