The Mag Grab Doublestack offers incredible holding strength in a compact design. Originally conceived as a trade show name badge, its smaller size proves perfect for wader straps and other narrow spaces. Machined from anodized aircraft-grade aluminum, this magnetic fly patch employs a rare-earth neodymium magnet to secure pliers, knives, and other tools. A high-grade stainless steel plate further resists corrosion, ensuring that the Mag Grab stands as a durable and high-quality fly fishing accessory.
