This tarp is 28' long by 24' wide with one 8' x 8' flap and 12” wrap-around skirts. If buying tarps for a 53’ or 48’ long flat-deck trailer, purchase two of these 24' x 28' tarps with 8' x 8' flaps to make a two-piece set that will cover your whole load. CanvasMart's lumber/trucking tarps are made from black light-weight 14oz heavy-duty vinyl for 10’ along the top of the tarp and 10oz heavy-duty vinyl along the sides of the tarp. The perimeter is reinforced with double-stitched webbing as well as rope cord along the edge for added strength. Perimeter grommets are standard, as are three rows of black d-ring rows at 32", 64" and 96" up from the sides. An extra reinforcing layer of 14oz vinyl is stitched under each D-ring for added protection and durability.
