Fits the Thule Aero Evo wing bar channel, much cheaper than OEM. Might also be handy in the equipment track on my Mocean Kayak.

Should work OK. They are functional equivalents to the original parts, though they are slightly different dimensions so will have a bit more play in the track. I don't think it'll matter once they're tightened down to my Rhino Rack Aero Bars and tracks.
Original Parts: 20.8 x 23.9 x 4.0mm
Replacement RR29TB: 19.9 x 19.9 x 3.7mm

The product itself is excellent. All around fit is perfect. The shipping was questionable. It went from Salt Lake to Vegas, (where I'm at) to South Dakota then Nebraska and on to Denver before making back to Vegas.

These worked great, but something to be aware of if you plan to use it with other tracks is that the tolerances are a bit loose. I used these in a Yakima track and some fit perfectly while others had to be sand/ground down a bit to slide freely or even enter the track. I'm sure the tolerances are fine for Rhino's track width.

Works for Thule crossbars that I own. About 1 mm thinner though. Using them for lighter loads but would still use Thule square nuts for heavier loads such as the hullivator. These are much more affordable though.

So far, so good for these Square Nuts to guide accessories on a Thule Slot Rack! I used them for a Thule Hullavator Kayak Rack.
