VEVOR Trailer Jack, 2000 lbs Dynamic Load Capacity, Heavy Duty Swivel Bolt-on Trailer Jack, 10" Lift Trailer Jack Stand with Handle for RV Trailer, Horse Trailer, Utility Trailer, and Yacht Trailer

Clamped perfectly onto the 2x4 trailer frame.

3 1/2 to 4in

They come with the bolts I think it’s about a half inch

I used 3/8" bolts and had to drill a size bigger. The supplied bolts are for a 2'"x4" tubular frame and look to close to 5/16" although they are more than likely metric.

Pretty sure you weld this thing on I did.

Anything bigger then around 4”.

People, if your model/year doesn’t show up when you look up the part then I would have to say don’t order it. You can also get the answer from the horses mouth if you contact the dealer/seller. No guess work on check work.

I used it on a new holland discbine

no sure I bought it and husband still in the box

I think that the mounting plate on the jack is 6 inches square, but I think that it has holes ro bolt to a 4 inch plate, or you could weld it on.

The bolt on/ weld on plate is 4”x 4”. The holes in that plate are 3” c to c. Should fit most anything.
