“8-foot Log Rack Cover,” Model 53444, is a textile cover with shaped corners to protect firewood from the elements. The log cover is composed of a 100 percent polyester woven fabric, dyed black and impregnated with polyvinyl butyral (PVB) on the interior side. The completed six-panel log cover with open bottom, measures 98 inches in length by 26 inches in width by 44 inches in height and is hemmed. The log cover features two front panels, a panel on each end, a back panel, and a top panel. The front panels are sewn to the top panel and meet at the front center. The sides and bottom of these panels are hemmed and are secured to the adjacent panels with hook and loop tabs. The cover can be tightened at the bottom using three one-inch-wide 100 percent polyester woven webbed straps with plastic buckle clips on each end. The side and back panels are secured in place by cinching an elastic braided polypropylene cord sewn around the bottom edge by connecting two plastic hooks located at each of the corners together.
