Hello Al,

Thanks for writing in!

The closest replacement cap I was able to find is the Replacement Cap for etrailer and Ram Square, Sidewind Jacks # TJD-7000S-CP which is 2 5/8". It has a clear zinc finish and is designed for select etrailer and Ram square sidewind jacks.

I've attached an image with the dimensions so you can compare them to your existing caps. Since these caps are designed to fit snugly over the jack tube, even a small difference in size can keep the cap from fitting securely. Before ordering, I recommend measuring the outside dimensions of the square jack tube, or if you still have one of the original caps, measuring the inside dimensions of that cap to make sure everything matches up.

If this cap doesn't look like it will work, just let me know the manufacturer and model number of your trailer jack, and I'll be happy to see if there's a better replacement available.

What kind of trailer are these jacks on?
