A "D" Tarpaulin is fire and mildew resistant as well as water proof. The tarp is made of a tough vinyl-laminated nylon cloth, yellow on one side and white on the other. The yellow is used as a caution tool for high visibility. The white side is used for light reflection when working in a dark area such as a manhole. This tarpaulin is provided with grommets for rope attachments. The "D" Tarpaulin comes in four popular sizes. "D" Tarps are also available in Custom Sizes!
