This 2x2' vacuum table was made just for the Shapeoko 5.1 Pro. You can fit a single one on a 2x2 machine, two of them on a 4x2, of up to four of them on a 4x4 machine. These tables are ultimately consumable, because mistakes will happen, and they might get gouged. If that happens, you can repair them with a bit of JB weld and a file, instead of having to replace the table itself. You'll need to pair this vacuum table with a vacuum pump to use it. What's included: 1x Vacuum table (24" x 24") 5 meters of 8mm Vacuum hose 5 meters of 5x5mm gasket 1x 8mm Hose fitting 1x Plug for the second air port Compatibility: Shapeoko 5.1 Pro Shapeoko 5 Pro The vacuum tables are 20mm thick, and are designed to mount to the T-slots in the Hybrid Table. Depending on your applications, you might need to add a sacrificial layer on top of the vacuum table to protect it from gouging. We recommend using MDF for this. NOTE: Our vacuum tables have a matte finish for additional friction and grip to reduce the chances of your workpiece slipping. Because of this finish, the tables will pick up a patina over time as you touch them with your hands, or get other oils on this. This is normal and does not affect the performance of the table.
