Nice stands. I use them in my hobby wood working shop. Retired my other older roller stands to backup status only.
Wish the Vevor stand had a set screw to keep the roller part from turning side to side.
There is a hole in the jack where I intend on welding a nut to, so that I can add a set screw to clamp down on the roller lead screw.
PLENTY heavy enough stands for my wood working needs.
