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.
Clamp
Worked for what I ordered it for. Fast shipping and a great product.
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.
Great speaker mounts!
Great products! Put them on my down tubes on my Vulcan to mount my speakers on them. Worked perfectly!
highway peg mount.
Better then i expected. Beefy, not some lightweight piece.
