ABSTRACT:
An adjustable frame assembly to hold auto bodies of unit body construction for straightening of bent and damaged portions thereof. The frame is comprised of telescoping bar assemblies for each side and each end, including a tubular bar member and an insert bar member received therein movable inwardly and outwardly to adjust the frame both longitudinally and laterally to fit whatever auto the frame is to be used with. The frame has projections at each corner for anchor members to receive and bolt to the floor. As an alternative, eye or ring members are provided for connection of chains to anchor the frame in that manner. In that case, lock bolts are provided to hold the insert bar members in fixed position relative to their corresponding tubular bar members.
