The AA configuration is simple and clean. Two “loop” or ‘U’ style end caps on each end of the system closes off the holes of the side rails, and leaves an open ended rack for cargo such as ladders, canoes, and surfboards.

The AB configuration is simple, yet versatile. The ‘A’ front is composed of two “loop” or ‘U’ style end caps at the front of the system. The ‘B’ roller on the rear allows for easy loading and unloading. It also protects your roof line and any high mounted brake lights or reflectors from accidental loading/unloading damage.

The EB configuration is ideal for hauling larger and longer cargo. The ‘E’ front end acts as an extension to the overall system by adding an extra cross bar up front. This crossbar adds an extra 19.5 inches of space to the H2.1 system, and allows for fog lights and other clamp-mounted accessories to be seamlessly integrated to the system.The ‘B’ roller on the rear allows for easy loading and unloading. It also protects your roof line and any high mounted brake lights or reflectors from accidental loading/unloading damage.

The DD configuration utilizes a 40 degree angled faceplate for both the front and rear end. The angled front faceplate acts as a wind foil, and reduces drag as well as wind noise when traveling. It also channels air over and around any low profile cargo like ladders and folding tents. The rear angled faceplate reduces drag and wind noise by allowing air to pass over and around it in a smoother fashion. It should be noted that both the front and rear end can be installed upside down in order to turn the entire system into a large roof basket.

The FD configuration allows for the integration of fog lights without compromising cargo space. The ‘F’ front end extends the system by 19.5 inches, as well as adds a lower bar to mount accessories to. There is an 8 inch space between the bottom and top rail of the ‘F’ piece, which allows for a variety of fog lights and lightbars to be mounted. The top rail of the ‘F’ piece falls in line with the rest of the cross bars, so laying platforms, cargo or paneling can be done seamlessly. The rear ‘D’ faceplate is angled at 40 degrees to reduce drag and wind noise by allowing air to more easily pass over and around it. Please note that the ‘D’ piece can also be installed upside down to create a basket style rear end for the system. *fog lights NOT included*
