The bolt holes on the etrailer Round, A-Frame Jack, item # TJA-5000S-B, triangle mounting flange are 3 inches from center of one hole to the center of the next hole. They are equally spaced apart and they are elongated for easier installation.

A-Frame jacks are all the same size and have the same bolt-pattern. The manufacturers did this so they could simplify the manufacturing process for both bolt-on and weld-on A-frame jacks.

The jack can be bolted on, hardware not included, or it can be welded on. If welding the jack to the trailer frame be sure to use a qualified welder.
