Product Description Master your jobs with ease with the Greenlee 860-4 PVC Heating Blanket (catalog number 860-4). A favorite of electrical experts, this premium PVC blanket makes it quick and simple to create bends with a 16-inch radius, offsets, or saddles in 3-1/2-inch to 4-inch PVC pipes. It's easy to use - simply wrap the blanket around the PVC conduit and secure it with the hook and loop strap, remove the blanket, and form bend by hand.
