Replaced a sheet metal shelf in the garage that was too long for a new vehicle. Everything fit on this though it was smaller, and it is sturdier than it looks. It was a little difficult to get all 4 plastic caps press-fitted in their sockets at the same time, and a couple popped out, which was not noticeable until the shelves were loaded with weight. It is probably easier with a helper, as would quick-clamps if they are long enough.
