18 oz Grain Trailer Replacement Tarps – Black | Shurlok Replacement Tarps

When you choose a Trison grain trailer replacement tarp, you’re getting a quality product built right here in our Texas facility. Unlike traditional stitched tarps, our grain trailer tarps are manufactured using a heat-sealed process that eliminates needle holes, loose stitching, and webbing that can wear out or rot over time. The result is a stronger, fully waterproof tarp that’s built to last.

Made from black 18 oz waterproof vinyl, each tarp is reinforced with 40 oz vinyl in the front, sides, and rear—where tarps see the most wear.

40 oz Bow Reinforcements (No Additional Charge)

To help your tarp last even longer, we can add 6″ wide, 40 oz heat-sealed reinforcements at the bow locations you specify. These reinforcements help reduce wear where the tarp repeatedly contacts the trailer bows—one of the highest-wear areas on a grain trailer tarp.

Simply provide your bow locations when ordering, and we’ll include the standard bow reinforcements at no additional charge.
