Electric Tongue Jack Recommendation for A-Frame Trailer with 2-1/4 Inch Mounting Hole
Question:
My travel trailer currently has a manual tongue jack with a hole of 2.25 inches. Does a replacement electric tongue jack also need to be 2.25 inches, or can it be only 2 inches? Will the 2 inch top plate be enough to hold it in place? Or maybe the a frame has a larger hole and the top plate is all thats used anyway, Im not sure. Does a 2 inch top plate and 2 1/4 inch top plate have the same overall size and have the same mounting hole pattern?

To answer your question, no, you do not have to use a jack with an outer tube dimension of 2-1/4 inches. An electric jack like the Ultra-Fab Electric A-Frame Jack, # UF38-944017, with a 2 inch outer tube diameter can be mounted on your travel trailer even though the jack mounting hole is 2-1/4 inches in diameter.
When it comes to installing the jack, the mounting flange was designed with slotted bolt holes to allow for installation on an a-frame trailer with a 2 inch or 2-1/4 inch opening. If you take a look at the installation video that I have attached for the Ultra-fab jack, just before the 3 minute mark, you will see where our installer measures the opening on the trailer that he is working with and it also has a 2-1/4 inch opening.
As for the stability of the jack, the lift capacity is 3,500 pounds whether it is mounted in a 2 inch or 2-1/4 inch mounting hole so I feel it is safe to say that welding the jack to your a-frame or securing it with bolts will be sufficient.
If the size difference is still a concern, you may want to take a look at our Bulldog Powered-Drive Trailer Jack, # BD500187, which has a 2-1/4 inch outer tube diameter and still offers a 3,500 pound lift capacity.
