This is a really good quality mount and a lot stronger than you can see from the photos. After receiving it, I decided to go a different direction with my trailer. My trailer is mostly an L-shaped corner, not a box. I realize I could weld another piece to make the box and then attach it as intended. Instead I just took the head and welded it to the side rail of the trailer and then mounted the tire. A NOTICE. The bolts that come with this kit are SCREWS that are used to attach the tire, not cleats like you have on your wheels. Don't expect to replace the included nuts with jam nuts, so you can just use your wrench to install or remove the tire. I don't know why they did it, but you'll need to bring a socket and ratchet just in case.
