• APPLICATION

    Hidden fastening for structural screws in structural composite lumber. Plugs are made from actual board material to match perfectly. Installation is a three-step process utilizing a pre-drilling and countersinking tool, screws, and plugs. All components must be used together as instructed to ensure proper function.
