Aftco Unibutts are the combination handle-reel seat that revolutionized trolling rod butts. Unibutt fishing rod butts are formed from the finest marine alloy using AFTCO's unique "swaging" process (see additional info section), the ONE-PIECE Unibutt aluminum fishing rod butt and reel seat is "unitized" for maximum strength and minimum weight. The aligning pin-plug, gimbal and fixed hood are locked in permanent alignment so that gimbal, reel and rod guides always line up perfectly. The ferrules are precision-machined to ensure complete interchangeability of rod tip sections, and an "O" Ring on the ferrule prevents corrosion between ferrule and reel seat. A *Teflon ring inside the collet nut assures a snug fit, prevents galling, and allows easy removal of the nut.
