The Mag Grab™ 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™ Delta  is a good one. The Mag Grab Delta can be combined with the Mag Grab™ Plus and/or Mini for ultimate organization.
