These are super thick and nicely made. The only reason i gave it a 3 star on the features is that i wish it had a flat bar welded on the bottom to keep the forks from being able to cantilever if you attempt to pick up something on the end of the forks.
Fits over my 36" forks easily. There is a little more side to side slop than you would have with a name brand fork extension, but its not a big enough issue for me to justify spending more on the U-line ones.
