Once cornerboards are installed on a building, contractors must hide the nails or screws that hold them in place. A one-piece VERSATEX PVC corner—the Stealth HF Corner—eliminates the labor-intensive patching, plugging and touch-up. The hidden fastener saves time and improves appearance in lap-siding construction while providing zero maintenance and weather-resistant properties. Building-supply dealers across the country stock the 1- by 6-inch (nominal), matte-finish component in 20-foot lengths. The Stealth HF Corner is compatible with most cedar, fiber-cement and vinyl siding.
