What is the Angle of ProSeries Weld-On A-Frame Trailer Coupler # PSE338050303


what is the angle of the A frame coupler


Expert Reply:

Typically an A-frame coupler will have a 50-degree angle. This is the case for the part you referenced, # PSE338050303 from ProSeries.

If you wish to measure your trailer frame to confirm its geometry you can do so with a protractor; please refer to the linked photo. Place the protractor on the inside edge of one side of the trailer frame; the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor.
