Mag Grab(TM) - Delta The Mag Grab(TM) Delta is a revolutionary new way to hold and store your favorite flies, tools, and more for quick access. Magnetizing onto an adhesive backed anti-rust steel plate, this magnetic fly patch is designed to be semi-permanently attached onto any smooth surface such as boats, coolers, vehicles, and more. Combined with our custom-made bottle opener, you can ensure every trip on the water with a Mag Grab(TM) Delta is a good one. The Mag Grab Delta can be combined with the Mag Grab(TM) Plus and/or Mini for ultimate organization. Product Info The magnetic fly patch is made from an aircraft grade aluminum alloy that will stand up to years of use. The aluminum housing holds extremely strong, rare-earth neodymium magnets 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. On top of that the stainless steel plate is a high grade stainless steel alloy that holds firmly onto the magnet, but will still resist corrosion, and last for many years to come. Dimensions 6" x 3" x 1/2"
