Using the BORA CT9 Work Support is easy. First, unfold the unit. You can place it on a flat surface wherever you need a workspace. If you want to cover the entire 4ft x 4ft area, you'll need to attach two CK22T Tabletops (not included). This work support can handle up to 3500 lbs, so you can safely use power tools or place heavy machinery on it. For taller users, the 36 - inch working height provides a comfortable working position. If you need even more height, just add the Centipede 6” Risers. When you're done, fold it up using the included carry strap for easy transport and storage. As for maintenance, keep it clean from dust and debris. Since it has wood dust Prop 65 warning, make sure to use it in a well - ventilated area. Check the polymer P - Tops regularly for any signs of wear and tear.
