ABSTRACT:
A compact foldable mechanic's walk for facilitating servicing of motor vehicles by improving access to the engine compartment. The mechanic's walk includes a pair of relatively narrow elongated planar mirror image platform members hingedly connected together along abuttable acute angular ends. The platform members are supportable by a plurality of pivotally supported legs adapted to be folded in against the bottom surfaces of the platform members. The platform members preferably are flanged so that in folded condition the in-folded support legs are enclosed within a box-like enclosure.
