Tarps Direct Harpster Tarps 7' x 20' Silver 6.0 oz 11-12 Mil Poly Tarp

Heavy-Duty Silver Poly Tarp

This 7 by 20 foot silver tarp is built from 6.0-ounce UV-treated polyethylene rated at 11-12 mil thickness. It is waterproof, mildew, acid and tear resistant for reliable outdoor coverage. The material blocks 100 percent of sun rays to keep covered items cooler. Rustproof aluminum grommets spaced every 18 inches provide secure tie-down points.

Upgrade from Lightweight Covers

It replaces thin blue tarps that tear quickly and let sunlight through when you need durable, long-term protection. The jump is worth it for seasonal storage of vehicles, boats or firewood where UV damage and water ingress are concerns. It also suits builders and campers who need a cover that survives repeated setup and takedown. Buyers who only need a quick dust sheet for indoor painting will find this weight unnecessary.

Cut-Size and Grommet Limits

The tarp is cut size so it will measure approximately 6 inches or 3-5 percent shorter than the nominal 7 by 20 foot dimensions. Grommets are placed roughly every 18 inches along the edges and at the corners only. Tie-down spacing is therefore fixed and cannot be adjusted for custom anchor points. No reinforced corners or additional tie-down loops are included beyond the standard grommet pattern.
