Designed for rugged use and continuous outdoor exposure, the Weathermaster Heavy Duty Silver/Black Tarp will provide optimum protection. Both the Black and Silver sides are UV treated for extended use in sunlight and are heat and cold resistant. The Black side of the tarp will absorb heat and divert ultraviolet rays. The silver side of the tarp reflects the sun's harmful rays. Each tarp contains 18" grommet spacing and black reinforced corner patches.
