Mounting Bolt Pattern of the Bulldog A-Frame Jack and is Hardware Included


need to know if your jack fits the existing holes in my trailer...............Thanks


Expert Reply:

The bolt holes on the Bulldog Round, A-Frame Jack, item # BD1700100317, 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 weldor.
