Abstract

A latticework assembly is provided. The latticework assembly includes a plurality of base laths and plurality of cross laths. Each base lath of the plurality of base laths is spaced apart from each other. The plurality of cross laths extend transverse on the plurality of base laths. Each cross lath of the plurality of cross laths includes a floor that separates opposing sidewalls extending therefrom. Each cross lath of the plurality of cross laths includes a cover. The cover includes opposing sidewalls depending from an underside of the cover; each of the opposing sidewalls of the each cross lath of the plurality of cross laths includes; wherein each of the opposing sidewalls of the cover include an outwardly directed hook. An inwardly directed hook that is engageable with the cover; and the outwardly directed hooks from the cover engage the inwardly directed hooks of the cross lath.
