Senco’s SHD150XP pneumatic nailer is designed for installing Mantis hidden deck clips (senco.com). A rare-earth magnet in the nose piece holds the clip in place, and an aluminum slide attachment guides deck clips into the proper position for installation. The paper-collated fasteners used in the tool are driven like nails and have square-drive heads so that they can be backed out like a screw if needed. The driver weighs 4.6 pounds, features a dry-fire lockout, and has an adjustable rafter hanger. It carries a five-year guarantee and is available on line for about $300.
Mantis clips are available in three common groove heights to fit most brands of grooved decking. The clips are designed to lift the deck board off the joist slightly to provide airflow and prevent water from being trapped between the bottom of the decking and tops of the joists.
