What to know before buying

The listing’s size fields are not fully consistent: it calls the finished tarp 10x20 Feet-Finished size but also lists dimensions as 240"L, without a width in that dimension field. The listing describes the grommets as metal in one place and aluminum in another, and claims UV resistance without giving a test or duration. Customer feedback is mixed on perceived thickness and size, so confirm the dimensions and whether 9 mil suits your intended exposure and tie-down tension.

Frequently asked questions

What size is the RAINDEWAY tarp?

The listing calls it a 10x20-foot finished-size tarp, but its separate dimensions field says only 240"L. Confirm the full dimensions if exact coverage matters.

What material and thickness are listed?

It is listed as polyethylene (PE) and 9 mils thick.

Can it be tightly tensioned with rope?

The product information says the grommets are suitable for medium tension and are not designed for excessive pulling forces.

Are the grommets aluminum?

The product details call them metal, while the accompanying Q&A specifies aluminum and spacing every 35 inches. The listing’s wording is inconsistent.
