RaceQuip SFI 27.1 Rated Adjustable Mesh Window Nets are constructed using heavy-duty polyproylene mesh with nylon thread for maximum durability. RaceQuip utilizes a jig-built construction technique to ensure consistent size, shape, and fit. This mesh auto racing roll cage net features a vertical ribbon which is necessary to pass the SFI 27.1 specification. This window net is designed to fit a window size of 18" High X 24" Wide. The heavy-duty 2" wide, extra long bottom straps allow you to mount the net directly to a door bar without the need for a lower window net mount kit. Available in black only.
