Question:
Hello, I’m looking for a replacement boat trailer jack with a 2-3/4” x 4” fixed mounting on my trailer. The existing jack had a 2220 stamped on it. I can send pics as well. Thanks

Thanks for reaching out and providing photos, Felix!
I took a look at our trailer jack replacements but none of them have that same style of mounting bracket. You might be able to find a direct replacement somewhere, but from my knowledge that's an older style bracket that will be hard to find.
For your application I recommend using the etrailer Boat Trailer Jack w/ Wheel # MJ-1206B instead because it comes with a clamp-style bracket and is rated for 1,000 lbs tongue weight so you get a little bit more when it comes to strength.
I'm attaching a review video of this jack for you to check out.

Hey Felix, how did the etrailer boat trailer jack with the clamp-style bracket work out for your trailer? Did it end up being a good fit for your mounting setup? Your update could make it easier for the next person with the same older-style bracket.
