Variable and practical. The shelves of the PROGRESS series 500 T are made from high-quality furniture steel and can be assembled in minutes using the screwless plug-in system. One difference lies in the addition of the empty shelves. These empty shelves, along with the corresponding accessories such as a hanging file drawer, allow for a setup tailored to your individual requirements. Further customization options include a back panel, top, and base in light gray (RAL 7035) and various dimensions. Shelves without a back panel, side end panels, door attachment kits, etc. - see accessories. Safety note: Shelves with a height-to-depth ratio of ≥ 5:1 must be secured against tipping (wall or floor anchoring).
