In designs where part of the Countertop is spanning between supports, the length of the span shall be limited to 2' 0" for 3/4" (2cm) stone thickness and 3' 0" for 1 1/4" (3cm) stone thickness. In designs where the Countertop is cantilevered beyond the supports (overhanging), the cantilever shall be limited to 6" for 3/4" (2cm) thick Countertops and 10" for 1 1/4" (3cm) Countertops, but in no case may the cantilevered portion represent more than 1/3 of the width of the Countertop. Cantilevered Countertops exceeding these dimensions will require Corbelled supports beneath the stone. The exposed underside of the cantilevered portions of Countertops will be sawn or otherwise unfinished. NOTE: Stones of lesser soundness may require Corbelled supports for cantilevers that are less than those specified above.
