I am going to use it on the Pro series cargo rack which seems to fit with some pounding. This rooftop carrier was ordered because our car, Camry, does not have roof racks, and we needed to haul quite a bit more than the trunk of the car holds. Wide fit was too wide However, I then foolishly tried to do overhead rope tricep extensions. Also includes a micro USB ear bud w/ each so u can plug in to BT for music or videos that I did not know came with it. Everything is so well defined and the stereo separation is perfect. fit meet perfectly in size 5. I love Italy so that really drew me in. Using to hold hand towel in guest bathroom. I asked MyGift for a replacement, not for the entire product, but just for the top swivel arm.
