You weld the kit. The tubes are laser cut are easily fitted for welding. The 5/8 inch holes located on the top frame are spaced 2 inches apart. Additionally, there are 128 @ 6mm tapped holes for you to mount custom fixture plates. We are not including the casters or caster mounting plates. I assembled and welded our table in about 2 hours by myself. We built this table for welding frames in our shop. It has been a great addition as it saves us a tremendous amount of time and money. The table rotates 360 degrees putting the work in a comfortable position for welding. Our weld quality has improved immensely. Table Dimensions: 96 inches X 38 inches.
