The Extreme Max 3006.8621 Triple Rod Holder for Kayaks is compatible with most rods, reels, spinning reels, open-faced reels, baitcasters, and more. The holder's post is designed to be mounted at any fixed angle and the angle can be adjusted at the base, letting you fully customize to your setup. Once the rods are in the holder, use the included rotating cuff to lock your rods into the holder and keep them secure until they are ready to use. The base attaches to any flat surface or track base, such as a boat gunwale or the Extreme Max aluminum Slider Base and nylon Slider Trax series bases.
