Hi Ken,
Thanks for your question and for giving us the opportunity to help!
The Ark Heavy-Duty Swing-Up Trailer Jack - Topwind - 10" Lift - 1,102 lbs # ARK79FR doesn't list compatible frame heights because it doesn't include the mounting backing plate or installation hardware. It's intended to be used with an existing mounting plate and hardware already installed on the trailer.
Based on the 5-inch-tall by 2-inch-wide frame you described, I don't see any reason it wouldn't work, provided you already have a compatible backing plate and mounting hardware that can be reused. Unfortunately, we don't carry those components separately for this jack.
If you're looking for a complete kit, I'd recommend the Ark Xtreme Off-Road Tube Mount Swivel Trailer Jack - Sidewind - 18" Lift - 1,650 lbs # ARK57FR. It's made by the same manufacturer, includes all of the required mounting hardware, and features dual 8-inch off-road wheels that perform well on surfaces like gravel, sand, and mud. It also offers a higher 1,650-lb weight capacity and additional lift.
Out of curiosity, what type of trailer are you installing the jack on? Also, do you specifically need the off-road wheels, or are you mainly looking for a swivel jack?
