It also features an exclusive, patented, all-climate engineered design that is 4-way fully adjustable for cold weather. The tonneau cover is also a great help in improving your truck fuel mileage. Corners do not buckle up due to parachute grade nylon corner reinforcements. Snaps and corners are backed with thick polymer forcing the corners and edges to lie smooth and look good in any weather. Extang's Monster Bows quickly spring on and off with no tools. It is fast and easily done with one hand. The TuffKlamps allow two bow heights: High for maximum water shedding in harsh weather, and for improved gas mileage. Low for sporty good looks and cold weather tonneau attachment.
