An excellent cover for all sorts of needs, this tarp protects your gear from the elements. Use it to keep outdoor projects dry during construction or cover a boat or car that is not in use. This silver heavy duty 20' x 40' tarp is made of durable polyethylene and has brass plated eyelets at 3' intervals making it great for tying down or hang it up as a shelter. All four corners have plastic reinforced patches and 4 strips of 4’ polypropylene rope attached, and all four sides are heat or sewn sealed for extra strength.
