FIRSTLINE ROLA FILE - An aluminium track system has been developed for the Firstline Rola File, as an alternative to the standard, heavier self based units. The design brief was to be able to provide an economical alternative to the standard self based models. Firstline aluminium track is not fastened to the floor, minimising damage to floor coverings, and allows far easier access for the user. These units provide great staff access, with no step up. Firstline Rola File units are extremely simple to relocate.
