A fast and easy way to install awning covers, this 6063-T6 aluminum awning molding features a mill finish. Also called awning rail, trailer molding, or awning track, this awning molding is designed to remain in place all year. The cover slides into place easily. 1/4-inch rope is sewn into hem at top of cover, then the rope-filled hem slips into the channel of the molding. This allows for easy installation and removal. PE Tubing, Vinyl Welt, or 8.5 m Keder Welt can also be used. #555 awning moldings are lighter in weight than #777, and are flexible enough to form and bend to varying shapes. The recessed mounting face conforms readily to uneven surfaces. This 180-degree #555 awning rail is 18 feet long.
