ABSTRACT:
A cover member that engages a hook member formed into a precast, reinforced concrete block. The hook member assists in the lifting, transporting and manipulating of the precast, reinforced concrete block. The cover member is formed of a water resistant, flexible and resilient material. Preferably, the cover member has a shape similar to a hat with the apex of the crown thereof being opened by way of an inwardly tapered aperture having at least one slit therein. The tapered aperture has an entrance portion dimensioned to accommodate the insertion of the head of the hook and an exit portion dimensioned to engage the shank of the hook. A slit of the aperture is dimensioned to allow the exit portion of the aperture to rigidly engage the shank of the hook as the precast, reinforced concrete block encounters movement.
