For a versatile, go-to tarp that provides full visibility, put a 20' x 30' heavy-duty premium clear poly tarp to the test. Even Mother Nature and all her extreme temperatures can't rock this three-ply, 14 mil polyethylene tarp out of its zone! This strong clear poly tarp offers artic flexibility and features a 14 x 14 mesh count, heat-sealed seams and reinforced plastic corners. All of our heavy-duty tarps are water and rot proof as well as tear-resistant. Each one is UV treated too, giving year-round protection from the sun's damaging rays. Grommets are placed every 36" to allow for a simple and quick tie-down. Clear poly tarps are an efficient choice for greenhouses and patio enclosures too. If you're covering an exact area, please make sure to measure before ordering. Finished tarps arrive slightly smaller. The finished size for the 20' x 30' premium clear poly tarp is 19'6" x 29'6".
