The raised side rails are the rails running from front to back on your vehicle which have space between the side rails and the vehicle. There is enough of a gap that you could slide your hand underneath. Raised roof rails are typically on SUVs of all sizes.

The crossbar can be adjustable to fit most SUVs and cars with 34.5" to 49.5" racks. The rubber strip across the top of the cross-bar virtually eliminates wind noise; wind noise and vibration are problems with many square and round bars.

The rack legs have rubber pads on both the body of the leg (outer part of clamp), and the inner clamp. The thick rubber pad on the body of the clamp. The mechanism that provides the clamping power is inside the cross-bars. The clamp is tightened (or loosened) by removing the nuts using an Allen wrench tool.

The plastic endcaps protect the interiors and give your roof rack an aggressive look. It also comes with additional 2 caps (6 pieces). The keys will help you remove them anytime and also help with security against theft. Please keep them carefully.

The maximum load capacity is 200 LB, making it very easy to load snowboards, skis, bikes, kayaks, luggage, and roof bags.
