The newest addition to National Nail Corp.’s lineup of decking installation tools, the Camo Marksman Edge was designed for use on treated-wood decks, which are often installed with no gaps between boards to allow for shrinkage. With the Edge, fasteners can be driven at an angle through the edge of a board, keeping the top of the deck unblemished. It can be attached to any drill and incorporates a built-in driver bit that controls the depth of the drive. The Edge also can be used with spacers when the installer wants to leave a gap between boards. National Nail Corp., 800.968.6245,
