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 hook 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. Stronger, lighter, and simpler, AFTCO Unibutts are available in Silver, Black, and Black/Gold anodized finishes. AFTCO Unibutts are standard among big game offshore fisherman. Available in either standard chair tackle lengths, or in short models built for stand-up angling.
