Abstract
Abstract This invention is directed to a sheet molding and in particular a molding that is used to assist in fastening corrugated fibreglass sheeting to supporting objects. The invention is a pre-fabricated section suitable for use in supporting corrugated sheeting comprising a hollow, open-bottom, elongated, body section, the body section having a corrugated top wall and two generally planar side walls; one or more nail receiving openings penetrating the interior of the corrugated top wall; a tongue located at and projecting from one end of the body section, the tongue having at least one pin projecting vertically from the surface of the tongue that corresponds with the corrugated surface of the body section; and at least one opening in the corrugated surface corresponding in size and respective location with the pin located on the tongue at the opposite end, located at the end of the body section opposite the tongue.
