Safeguard your sensitive equipment from dust, debris, UV rays and other job site hazards with poly machine and equipment covers from Canopies and Tarps. The covers are made of durable seven-ounce polyethylene, so they have a solid feel and are thick enough to offer excellent coverage. The covers are pre-formed and sewn along the edges to create a rectangular shape that slips easily over your equipment without the need for additional ties, straps or accessories. Working in a humid environment? The silver industrial equipment covers are also great at keeping moisture away from your machinery, helping to preventing rust and corrosion.
