When you have to go big or go home, the 170' x 170' tarp will get the job done. This is the largest tarp size offered by Canopies and Tarps. This tarp will cover an enormous area and is sure to provide enough coverage for anything that you need. As these tarps are of an unusually large size, we are only able to offer them in one style and limited colors. Our largest tarps are made of heavy-duty six-ounce polyethylene that is 12-mil thick and features a 14x14 weave. These tarps come in white, tan and clear.
