The Sto-Sack® is a blower hose that is designed to move large volumes of air using any blower. It features a flexible, single-ply, PVC-laminated, polyester fabric blower hose supported by helical steel wire that compresses at a 10:1 ratio. The bright yellow, flame-retardant hose has a belted cuff end that fits into any blower and is protected by an external wear strip, the company said. The mildew-resistant hoses come in 6- to 24-I.D. sizes and standard 15- and 25-foot lengths. Special lengths and commercial and military colors are available. The hose fits into a self-contained storage sack. Applications include ventilation, dehumidification, and temporary heat or air.
