Availablar 12x40 Silver Heavy Duty Canopy Cover
Waterproof
Woven Polyethylene: 14 x 14 weave count.
HEAVY DUTY: 6 ounces per square yard; 12 mil thick.
Aluminum grommets are spaced approximately every 18 inches on all sides and corners.
We recommend using every grommet or at least as many as possible to equally distribute the pressure around the entire perimeter of the tarp. This increases the longevity of the tarp and decreases the likelihood of having grommets tear out.
