Abstract: A rigid, metallic clip and a method for providing hard fastened, anti-racking ceiling and wall construction. A flat, perforated body portion bordering an integral, perforated tab extends downwardly from a junction at the midpoint. A pair of spaced apart and parallel fingers projecting forwardly engage the top plate, snugly resting beneath insulation to temporarily retain clips for screwing. A pair of elongated, reinforcing grooves extending from the clip rear to the junction are convex, so the bottom of the clip flushly mates with the ceiling sheet. The rigid, integral tab projects downwardly at a preferred angle of eighty-seven degrees. Clips positioned on the top plate are fastened by screws that penetrate the tab. The horizontal ceiling sheet can then be screwed to adjoining clips. A sidewall sheet disposed substantially vertically is then screwed to framing. The sheets cover the clip body, and no jagged edges or sharp points remain visible.
