Question:

Looking for a jack for gooseneck trailer 4.5 wide. No bigger. 22.5 long is the weldable portion of jack. Spring loaded. Id say around a 12000 lb one. Old one is a binkley 48000 SL if this helps. Just looking for correct jack to weld on there. Fits between 2 braces so the 4.5 wide is a necessity no biggier

Hi Shawn!

I was able to find a little info on the Binkley 48000 SL you need to replace, and it looks like the etrailer Square Jack w/Handle - Foot Lever - Drop Leg - Spring Return - 12K Lift - 26.5" Travel # TJDDP-20000SP-F will be a pretty close match.

The weldable portion measured 22-3/4" when I checked one in our warehouse and it is 4-3/8" wide, so you are good there as well. It has 12,000 pounds of lift capacity and 20,000 pounds of support capacity, so it meets that need as well. Of all the ones we have, I think this will be the best option for a replacement.

Out of curiosity, are all these part you have been ordering for the same trailer?

The extension worked perfect and was priceless for me as I did not move my plug location to hook up the gooseneck, just left it down by my bumper/pull mount and ran the extension to it.
