RidgeClip

The clips have a rubber or vinyl pad that sticks to the surface that grabs my factory rails. This is an obvious wear item. You cannot buy the pad itself, you have to buy a new set of clips for $144. If they are not right, the rack will move while driving. They do also fall off easily when assembling and when removing from the roof, pull the whole assembly off the roof and tighten down while holding the clips together. this keeps them in place for storage. Place assembly back on roof, and open just enough to fit inside clip, while holding outside clip. Then you can hold inside clip against rail, and do the outside positioning and then tighten. I wish I had gone with a trailer hitch or the BMW factory rack.

Thank the gods (whichever you prefer) for the new Sightline. The Sightline uses the same Ridgeline Clips and the Yakima web sight now provides measurements taking away all the guess work needed for the Ridgeline. The Sightline has spring clips to hold the front and back Ridgeclips/Sightclips on the hooks on the towers during installation. The Sightline is lower than the Ridgeline and looks better after installation. Now if Yakima would put some threadlock on the 4 screws that attaches the tower to the crossbar on all of their towers we would be even more enthusiastic about the their racks.

I work in a store where we sell and install Thule and Yakima racks. The Ridgeline system for flush siderails is the most persnickety of the four types: Basically it is like a Baseline but with (4) four extra clips on the backside of the tower so there are a total of (8) eight clips for a two bar rack. The other thing that makes this system a PITA to install is the way the clips "hang" on the tower. The clips are quite easy to dislodge from the "hooks" that go through them until the rack is tightened in place. Like I said: persnickety. Once it is on it works fine. Apparently there has been a redesign ... so maybe wait if you have a car with flush siderails that takes the Ridgeline towers and clips. : )
