The extruded aluminum profile shall incorporate a continuous integral fin for surface contact to conventionally installed gypsum drywall. The fins shall be 7/8" wide and shall be tapered to the edge. The tapered fins shall be punched with holes staggered to accept standard screw fastening. A series of continuous grooves shall be extruded into the face of the fins to provide greater bonding surface. The extruded profiles shall be primed with corrosion-resistant primer compatible with materials normally in use in conjunction with commercial interiors, i.e.: joint compound, latex and enamel paints, and wall covering adhesives

For use with conventional metal stud construction and 5/8" GPDW only. The SWB-400-8 will permit construction of a wall base which provides a recessed surface to receive vinyl or other cove strip material. The bottom is thinned to allow scribing to irregular surfaces. Screws through the grooved fins must always engage metal or wood substructure to ensure proper installation.
