NEW AND IMPROVED! dbl the amount of adjustments, easyer adjusting, new hammer logo. Made out of 11 gauge stainless steel so they will never rust. Built to fit a 3/4" (.75") axle. If you have a 1" axle they can easily be drilled out to 1". They can be used on any flat axle plate, all you have to do is mount a post for them to rotate against. I like to use a 1/4-20 socket head cap screw.

Check out the video on the blog to see how they work.

Sold in pairs.
