You can use this to build a workbench! This Parf Guide System provides a very accurate, yet quick and easy method of making a grid of 20mm holes in a workbench table or on the top of an MFT table. With an accurate hole pattern and a set of benchdogs you are able to make perfect 90° and 45° cuts with a guide rail and plunge saw. The PGS provides a simple and efficient way to provide as many individually custom sized worktops with rows of holes or to create portable worktops - handy on location if you have a lot of cutting to size. https://www.youtube.com/watch?v=5usysrkgQBo
