Abstract
A method and apparatus for preparing slabs of material such as granite for transportation and erection. The apparatus includes a cutting bit and means actuating the bit into the face of the slab so as to form an arcuate slot, widest at the bottom, centered outside the slab. The slot may be dove-tail or inverted-T in configuration, to receive the heads of conventional fasteners, by means of which the slab may be hoisted or transported, as well as being finally secured in its ultimate facing or other location thereby.
