Compatible rod diameter: Φ5-16mm The "Multi Hook Keeper (MHKM)" is an add-on hook keeper that is easy to attach without the need for thread wrapping or resin coating. It can be attached to rods with diameters of 5-16mm using the rubber ring. Its most distinctive feature is the newly developed W-lock mechanism (PAT.P) for safety and security, which further holds the fishing hook with the body after it's hooked, preventing lure detachment more effectively than conventional products. Additionally, it features an open-type stainless steel hook, allowing you to set the hook point of offset rigs without pulling it out of the worm, and also to set the sinker part of drop shot rigs. To prevent line tangles during casting or retrieving, it has a flat body designed with the lowest possible overall height when folded. By attaching this item near the front grip, you can further reduce line tangles during fishing trips. The pulley and rubber ring are all black. ● About product images Product images are representative images. Please note that they may not always match the product name.
