Formed from the finest marine alloy using Aftco's extraordinary swaging process, the one-piece Aftco Unibutt 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 guides line up perfectly. 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.
