The Starborn Pro Plug System for Fiberon Decking - 375 Plugs only is a superior and easy-to-install plug fastening system for Fiberon Decking. When used in combination with epoxy coated or stainless steel fasteners, it gives builders the ability to choose the right screw for a wide variety of applications. Due to the density of Fiberon decking, the boards require a pre-drilled pilot hole prior to screw & plug installation The system features the PVC Tool (which drives screws to the correct depth without stripping the screw recess or damaging the deck board surface), and plugs made from actual deck and trim material. When using the PVC Tool, the fasteners create a perfect hole for the matching plug. Note: Screws and Pro-Plug Tool for PVC and Composite Sold Separately.
