A stabilization apparatus for a frame having a cover comprises a lifting head having a horizontal shank with first and second ends, a pair of vertical supports, a vertical support located at each end of the lifting head and a retention leg connected to the shank the retention leg in use configured to exert a downward restraining force on the frame or portion thereof. The apparatus prevents a frame or its edge from being lifted with the cover, and thereby reduce damage to the frame or road and avoiding costly repair. The inventive apparatus is particularly useful to prevent damage to manholes when lifting manhole covers.
