The boat bar is a magnetic fly patch made from an anodized aircraft grade aluminum alloy that will stand up to years of use. Its fully machined and milled aluminum housing holds extremely strong, rare-earth neodymium magnets rated for over 250 lbs of force which were specially chosen to be delicate enough so flies can be easily removed, yet strong enough to hold pliers, forceps, knives, or just about any tool you can imagine. The magnet is equipped with a high-strength adhesive backer so it can be permanently attached to any smooth and flat surface. The Mag Grab truly sets the bar as the new standard for high quality fly fishing accessories and tools.
