I built a large aerator for my pasture. I needed a different jack support. This bracket was the answer.
They will be great for my trailer as I didn’t want to have to weld a bracket on and end up melting my wiring for my trailer. I will take a picture of them mounted after the holiday
Nicely made plate … but be aware … the swivel extension may be too long for your jack to fit snuggly against the plate. For my jacks it’s useable but there’s too a lot of deflection hence there’s stress on the jacks. The deflection can possibly be mitigated in two ways with either a spacer or by drilling 4 new holes and cutting off 3/4 of an inch. I will try the spacer first. It’s still a better option than hiring a welder.
Exaclty when ive been looking for. I drill out 2 more holes to add to it rigidity. My trailers get hauled all over and pulled up and down rollback tow trucks. But yes great product. Very well made
Can be welded or bolted on or “both”. Very well made.
Great product.

Ordered the bolt on swivel jack mounts and they are great quality and exactly what I needed for our camp trailer. Also ordered the Thule leveling ramps, another outstanding product, thank you E trailer for having great prices and the parts we need!
Insanely fast shipping. Exactly what I needed and the quality looks great!
Just got through putting on the supporting brackets and one jack I made a mistake and only ordered one jack but called and the other one is on the way. These jacks will stabilize the cargo trailer that is my living quarters and transpot trailer when I go prospecting.
High quality piece. Perfect welds and f inish.
