We are wintering over on the beach (we are full time campers) and we needed to enclose our cabana. We ordered "roof" and "walls" . They needed to be able to stand up to serious rain, wind and sand blasting from beach sand. We are very happy. Sizes were as ordered. We wanted to have the tarps fit but still have airflow to prevent mildew. These tarps are perfect. Waterproof and the desert color is very nice looking.
Grommets are 18" apart NOT 24" as with others we looked at.
