Formed from the finest marine alloy using AFTCO's unique "swaging" process, the ONE-PIECE Unibutt® aluminum 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.
