VEVOR Carport Replacement Canopy Cover 10 x 20 ft, Garage Top Tent Shelter Tarp Heavy-Duty Waterproof & UV Protected, Easy Installation with Ball Bungees,Grey (Only Top Cover, Frame Not Include)

The fabric is not measured in thickness but in square gram weight. This fabric is 210g².

Was 6 inches too short and stitching was cheap

I just got mine. I have not used it, but looks to be very poor quality and very thin. I think it will probably fit most shelters because I don't think it has the nice corners that a COSTCO shelter has. I talked to COSTCO the other day and they are switching suppliers right now. None available for probably a couple months. I would get one of those.

No, this 12 by 20 replacement sidewall canopy will not work with your slanted-leg frame of the same size.

We do not sell separate frames. You can refer to this product: https://www.vevor.com/s/KFSJSQCCKHS8DE5CF001V0

While the product description doesn't mention anything about wind or rain resistance, customers mostly say it works well in moderate weather conditions. A few mention it holds up to light rain and winds, but heavy rains and strong winds may cause damage.
