Yakima Bar End Caps - Set of 4 $10.00
If you hit your head against the Bar End Caps, you still might knock yourself out, but at least you won't need stitches.
Yakima Bar End Caps, sold in sets of 4, are a handy piece of gear to have on your Yakima rack. End Caps protect both your head and your crossbars from bumps and bruises. Crossbars do not come with end caps, so if you're building a rack, pick yourself up a set of these to cap things off.
