Quick Facts:

  • Polycarbonate is the same material used to make police riot shields, astronauts helmet visors and airplane windows!
  • Polycarbonate has a 10 year manufacturer's guarantee against yellowing or cracking. It's infused with UV protectant to help it last longer.
  • The Polycarbonate cover is built with a 1.5" incline at the center of the back bar. This helps water run off the cover instead of pooling on the cover.
  • The aluminum frame makes the Polycarbonate style our lightest cover, But we don't sacrifice strength, it still holds up to 750 lbs!
