The PB Products X-Stiff Curved Aligner is a versatile tool for fast, easy hook changes on Multi Rig systems. It holds the D-loop securely in place and extends the hook shank for a more aggressive hookset. The aligner can be trimmed to your preferred length, and the line feeds centrally through it so any adjustments keep the rig balanced. The X-stiff Curved Aligners work particularly well with pop-up and "white pool" style rigs, giving you multiple options for positioning the hook during bait uptake. These X-stiff aligners rotate aggressively. With the pivot point sitting directly under the hook point, the hook is turned into the optimal position before it penetrates. They come in two sizes: one for hooks sized 1 to 4, and another for hooks sized 4 to 8, which also suits many size 10 hooks. - Highly rigid and sturdy, ensuring consistent performance - Rapid rotation due to its extended length for a quick, aggressive hookset - Sits perfectly on the hook for optimal positioning - Adjustable in length for customizable rig setups - Central line feeding makes adjustments simple and balanced - Remains securely in position on the hook eye
