Powernail is pretty much the Cadilac of flooring nailers.  They are built for the professional installer and can usually be seen in the rental department of your local big box store.  They take a beating and keep working every time.  This tool basically is a first of its kind.  It allows installers to now nail 5/16″ to 9/16″ tongue-and-groove flooring instead of using adhesive.  It is great for thin flooring and the Powernail cleats are designed to grab but still allow of expansion of the material.  Check out the Ultimate Tool Bag Giveaway 4 and the newly added Powernail 2000.
