Best Trailer Jack for a Boat Trailer with 3-1/2 Inch Wide By 5-1/2 Inch Tall I-Beam Trailer Frame

Question:

I need a trailer jack for my boat trailer. I need it to swivel, with a wheel, 1500lb, 10inch min travel and fit an aluminum I beam application. I Beam is 5 1/2inch OD high x 3 1/2inch wide. ID is 5. Which unit will fit my application? Thanks for your time.

I do have an option but what you are wanting is just simply not possible due to the dimensions of your aluminum I-beam frame. The only marine grade bolt-on trailer jack we have that will work for you is the Fulton Marine Jack part # HD50000101. The Fulton Marine Jack offers a 5,000 lb capacity and up to 14" of lift. The bracket used to secure the jack to the frame is positioned near the bottom so you should not have any issues with bottoming out. The zmax finish will ensure you don't run into any rust/corrosion issues down the road as it has a 5 year warranty. I have attached a review video for you.

I really wish we had exactly what you need but all of our bolt-on swivel mount trailer jacks max out at on frame rails 3" wide x 5" tall.
