For canvas covers and dodgers to work correctly they need to be tight. Unfortunately, getting a drum-tight fit often means trouble snapping down the fasteners. Surefas has solved this problem with its ingenious Q-Snap, a device that functions like a normal press fastener, except it comes equipped with an extra ring on the underside of the fastener and a small hook on the deck. Sliding the extra ring under the hook gives you the necessary leverage to secure your canvas, no matter how tightly it’s cut. Better yet, the hook and ring combo also helps keep the fastener secured after it has been snapped closed. Brilliant! $5.30. Surefas, surefas.com
