Do not buy this rack. I bought mine thru LL Bean and am returning it. At first i thought it was fine except for its extreme heaviness, making it not too desirable to take on and off the hitch between uses. Then i took a road trip from Tallahassee to Alafia State Park, outside Tampa, FL and its real deficiencies presented. Rhe rubber cradles move on the arms, apparently from road vibration. This caused the straps to unhook themselves. Fortunately, i had both the lock wrapped around frame and the frame lashed to the center column. I had to keep stopping on way there and back to keep readjusting everything and had to keep watching it in rear view mirror. Its unsuited for intended purpose. And for Thule's own advertising, the Thule lettering is not painted on but letters are decals which peeled off in a few weeks.
