Stabilizer Jacks Swing Down Trailer Levelers

I pictured swing down "levelers", that screw down. I had them on my pup, and have seen them on TTs. They just swing down as you turn the handle, instead of being a scissior. They work well, and do the same job as a scissior stablizer.

They are NOT levelers. The are only designed to stabilize the trailer, not to level it. You level the trailer side to side, and front to back. And then run the stabilizers down snug.
