Great Sturdy Rack

This is a great rack for my 1998 Jeep Wrangler with the Smittybilt SRC Roof rack. I was not interested in the other rack Smittybilt had to offer with the rack base, so I bought this one and used U-bolts (from the local hardware store) to clamp the rack to the base. The rack was packaged nicely in a thick cardboard box with foam padding inside. There were no dents, scratches, etc. The rack actually eliminated the additional wind noise from the rack base itself. Looks great on the Jeep and seem hold a lot. I was able to put two people on top and watch fireworks during July 4th. Just keep in mind the additional height of your vehicle with the rack. My Jeep lifted 4" with the rack is taller than 6'10" which cannot fit in most parking decks in the area.
