The WORKSHOP 2½ inch standard hose features patented Dual-Flex technology which provides 180° flexibility at both hose ends for enhanced maneuverability and resists crimping and collapsing. The hose also features crush resistant polyethylene material. The long 7-foot hose extends your cleaning reach so you no longer have to "tug" your vac around by the hose and deal with tipping-over issues. It's designed to fit most standard wet/dry vacs and accessories with 2-1/2-inch diameter.
