Longshot Enterprises Stock Lumber Tarps are fabricated in Kansas. The tarp material we use for our stock lumber tarps is 18oz vinyl coated polyester (VCP). We use a 14oz VCP on the sides to reduce the weight of the tarp. Our stock size is 24 foot length x 20 foot width with 8 foot drops and with a front flap. There are three rows of reinforced D-Rings. We use 2” polyester webbing along the length and 1½” polyester webbing reinforced with vinyl to attach the D-Rings. Longshots uses heavy 207 polyester thread in our double needle Lockstitch machines. Our tarps have #3 brass grommets in the reinforced hems around the perimeter of each tarp. This tarp weighs 82 lbs.
