Safeguard systems have emerged as one of the leading manufacturers of File Storage Compactors, which are movable filing cabinets mounted on a track rail. These specialized and uniquely designed office furniture units are usually constructed with a rotary handle on the exterior accessible face. The storage compactors are the only solution for your storage management solutions. When revolved, the handle operates the mechanism which winds the single, connected, filing unit either left or right, depending on a clockwise or counter clockwise rotation of the handle. By eliminating the need for an aisle between every shelving unit, more floor space can be utilized for storage. The tracks are leveled to eliminate gradients in the supporting floor. This makes it possible to move heavy units with minimal effort.
