So the standard angle for A-frame trailers where the two beams meet is 50 degrees. So while I can't get you a CAD drawing for the coupler part # CA-5400-B if you are trying to design your trailer to have the correct angle for the A-frame you should make it as close to 50 degrees as you can and standard couplers like this will fit and work well.
