Helpful Expert Reply:
The coupler part # CA5100B measures 9-1/4 inches wide and 8 inches tall where it attaches to a standard a-frame. The narrowest part of the angle of the coupler is 2". I have attached a diagram to show you the dimensions.

This is exactly what I need! I intend to use 2" rectangular tubing for the trailer frame, with a complete bridgework support system on top. Like a sprint car chassis. The whole trailer and contents should only weigh 600 lbs.

How tall is the coupler? In other words what is the size of the rectangular tubing that can be welded inside the coupler? You have shown the angle of the coupler and the width of the inside but not the height. Thanks
