The clamps fit great. They grabbed the cross bar perfectly. But the mounting hole is too big. The catalog said the hole is 3/8. But the clamps they set me are 1/2. The clamps are useless.

Incorrect description

Be aware, this is one clamp, not a set. That is not an issue, just pointing it out. <br /><br />The reason it got two stars is that the description clearly says it has 1/2in mounting holes. That is 100% incorrect. I bought two and they are much smaller than 1/2 inch mounting holes.

Highway peg bracket

The part description said they had a 1/2" mounting hole. They did not. They had a 3/8" mounting hole. Easily rectified with a drill bit and a drill press. Easy to install. Look great.

Better then i expected. Beefy, not some lightweight piece.
