Brownbuilt has a heritage of manufacturing filing cabinets that lead the Australian market in both engineering and design. Brownbuilt's stylish, contemporary slimline exterior design, featuring an aesthetic finger-grip alloy handle, is matched by superior internal engineering. For strength and stability, the carcass features a sturdy welded support frame, a welded top and a metal base plate. Brownbuilt's painted full height drawer body ensures that your files are fully supported and prevents files falling into the cabinet. A progressive ball bearing runner assembly fully extends to allow complete access to every drawer and has been tested with a 30kg load to over 50,000 cycles to ensure that it can stand up to the toughest treatment. The Brownbuilt filing cabinet runner system incorporates a standard drawer lock-out mechanism, which stops tilting by preventing more than one drawer being open at the same time. Buffers within the runner members prevent closed drawers from drifting open, for additional operator safety.
