The prong portion has a series of bends in its middle that extend over a lower portion of a similar wire mat located immediately above such that the series of bends interleaves with longitudinal members of the wire mat above. In a preferred embodiment one or more connecting pins are inserted between the prong portion and the longitudinal members of the mat above.
