Covercraft – Cab Forward Truck Cover (Part No.C11064D6)

Cab Forward Truck Cover

from

$838.99
Cab Forward Truck Covers are designed as a quick and easy cover solution to protect your truck’s cab and hood. Sunbrella provides protection and years of service in intense sun climates like Arizona and other areas of the Sunbelt, where UV rays can rapidly degrade the paint and interior. Because of the use of acrylic fibers, which are naturally UV resistant, Sunbrella has long been the recognized leader in longwearing marine fabrics for bimini tops, sail covers and deck enclosures. Besides marine uses, Sunbrella is also used for commercial awnings due to its ability to provide UV blockage, along with a rich, woven finish. The acrylic fibers are solution dyed, before the fabric is woven, to assure the color goes all the way through the fabric. Using a special finish process, the material is then softened for use as a truck cab cover fabric. The fabric is exceptionally strong and, coupled with its UV resistance, it also makes an excellent cover for RV’s and trailers that spend extended time stored outside.

Product Features:
  • Custom Protection for Front Half of Pickup
  • Great for Use with a Camper
  • Protects Interior From UV & Reduces Heat Build-up
  • Easy to Use
  • Cab Forward Covers Available in Multiple Fabrics
