I frequently get questions regarding the dimensions and construction of my loading arch. I’ve put together this page to illustrate the details of the arch for reference.
Modifying the arch to fit your needs is pretty simple. If you need more or less width than 62.5″, simply add/subtract your desired change to the top piece of the arch. If you need to change the height, add or subtract your desired difference from the uprights.
The arch itself is made from 2×3″ tube with a 1/4″ wall thickness. The gussets can be cut from a piece of 4″ wide flat bar.
