I got these to use with my MF40 loader to move pallets. They install easy, and work well. You need to use a tool for extra leverage to tighten them down - a large box end wrench works well. The only issue I had is that the crossbar doesn't get narrow enough for the smaller pallets, so I ended up not using it at all. Used some spray paint to mark the spots on the loader so I can easily reattach them at the right width.
