A slide and swing chassis assembly for electronic equipment which can be slid from an enclosure and swung to one side to permit complete access to equipment on the chassis, as well as equipment at the rear of the enclosure. The chassis assembly has a pair of chassis side frames which slide along slide members within the enclosure, one of the side frames having a pivotal slide plate attached to the rear portion which is pivotal from a closed position at the rear of the chassis to an extended position parallel with the side frame, such that the chassis may be slid from the enclosure along the slide members, and swung to one side while supported by the slide plate. A stop means is provided to move the slide plate from closed to extended position, and a restraining means is provided to prevent unintentional complete removal of the chassis and slide plate from the enclosure, with biasing means provided to also assist in moving the slide plate to closed position as well as in biasing the chassis to sideward position when swung on the pivoting means to the side of the enclosure.
