Anglers, give your fishing reel the upgrade it deserves with this KooingTech carbon fiber handle! Measuring 3.74 inches between knobs with a 0.67 inch frame width, this lightweight (just 42g) handle combines carbon fiber, wood, and metal for the perfect balance of strength and comfort. The cork knobs feel amazing in your hand and provide superior grip even when wet - no more slippery hands during those exciting fights! Installation is straightforward: just mount the metal frame and handle on your reel's load bearing, fix the screw nut, add the metal washer, and secure with the included screw. Works with most casting reels and spinning reels across different brands. If your reel bearing size is 5x8mm, you don't even need the metal frame for installation. The package includes everything you need: handle, 4 screw nuts, metal washer, metal frame, and frame screw. Perfect for saltwater fishing where corrosion resistance matters, or freshwater anglers wanting better performance. Whether you're building a custom reel or just replacing a worn-out handle, this upgrade will make cranking in fish feel smoother and more comfortable. Your hands will thank you after a long day on the water!
