RaceQuip® SFI 27.1 Rated Ribbon Window Nets are constructed of heavy-duty 1″ polypropylene webbing and nylon thread for maximum durability. RaceQuip® utilizes a jig-built construction technique to ensure consistent size, shape, and fit. This auto racing window net was designed with drag racers in mind and it has a very unique size (24″ H Left Side to 18″ H Right Side X 23″ Wide) and shape which satisfies many applications where a custom racecar window net would be needed. The SFI tag is placed in the center of this net so rows can be trimmed off of either side to make the net more narrow for a funny car type rollcage. SFI 27.1 certified and available in black, red, and blue.;
