The DuBose Strapping FDN 3/8" refers to an industrial-grade front-action, double-notch manual strapping sealer designed by DuBose Strapping. This specialized handheld packaging tool secures standard-duty, 3/8-inch-wide steel banding and metal open/snap-on seals. By pulling the levers forward, the tool crimps down on the metal seal to form a strong, high-reliability double-notch joint that keeps heavy cargo or pallets securely bound during transit
