This galvanised add-on unit allows you to expand the width of your chemical storage as per your needs. The end frame supplied comes assembled. Hook one end of the each shelf at any height onto the end frame and fix the other end to the main unit. It is possible to add any number of add-on units to expand your shelving. The units are designed for boltless assembly.

The end frame of the add-on unit can be bolted to the floor. It has four perforated shelves that let fluids through. The sump tray below the bottom shelf collects any spills efficiently. Add an extra shelf and sump tray as required (sold separately, see accessories).
