Query: Worked as well as expected, with modification

I have a set of Bil-Jax scaffolding and the solid top that it attached to this screw leveling jack didn't fit inside. All I had to do was remove it and just push the threaded shaft inside and it worked just fine!I'll be ordering more of these for times when I need to set them up wide instead of tall.NOTE: By altering it this way you run the risk of adjusting it too far and not having enough stability and collapsing. I recommend that you put a screw into the threads where the solid top was so that this doesn't happen.
