Question:

I just purchased two 5,000 etrailer and one Pro Series A-frame jacks. No where does it tell me the size and grade of bolt I am supposed to use. Can you help me out on this matter?

Expert Reply:

The etrailer and Pro Series A frame jacks will use 3/8 inch bolts, which is the standard size for A frame jacks and couplers.

There's a really good chance they use the same size (it's pretty standard) but it wouldn't hurt to reach out to Butler Products directly just to be sure. Unfortunately we don't carry their products so can't be 100 percent certain.
