Abstract: A laterally mobile modular storage cabinet system having improved anti-tip bracket secured to the wheeled carriage frame, and engaging the rail support pad. The anti-tip bracket is in the configuration of an inverted "T". The bracket includes an elongated leg portion with a cross-member forming a pair of transversely extending legs at the base thereof, and is formed of an acetal polymer with the repeating unit being oxymethylene, and with a melting point of between about 175.degree. C. and 181.degree. C. The rail support pad has a groove formed along the upper surface thereof to engage the anti-tip bracket, and the two transversely extending legs provide support to restrain arcuate tipping of the wheeled frame and cabinet enclosure from the rail support pad.

Abstract: An improved system for storing tape cassettes which includes, in combination, a tape cassette hanger means along with a rail support cooperating with the hanger means. The hanger means is arranged to be removably attached to the rail support, and includes a pair of rail groove-engaging hook members which extend outwardly from a backing, with the upper hook member having an outer tip of generally arcuate downwardly converging configuration, and with the lower groove-engaging hook member being of generally linear configuration with a horizontally projecting first segment extending outwardly from the base and having a rail groove-engaging flange at the outer tip thereof.
