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.
