This rack fits 3 420s the traditional way OR 6 Optis, side entry, 2 per level. Trailer compatibility is critical with this rack. The ideal trailer is 64" between fenders and is at least 36" wide at a cross section located 100" forward from the back of the trailer (where the bottom forward cross bar will mount). Alternatively, we can modify this rack to fit on a trailer frame that is wider than 82" between fenders. In this case, the bottom cross bar would have pegs that extend out for mounting.
