Boat anchor lock and roller assembly — 304 stainless steel frame with nylon roller (roll size 42 x 63 mm, 10 mm mounting hole) Key benefits Protects your boat hull and gunwale: the anchor lock keeps the anchor lead from rubbing directly against the boat, reducing repeated friction damage. Smooth anchor handling: the nylon roller guides the lead for easier deployment and retrieval with less binding. Durable and corrosion-resistant: the anchor frame is made from 304 stainless steel for reliable performance in marine environments. Simple installation and secure fit: pre-drilled holes are provided for straightforward mounting to most anchor lockers or bow areas. What this part does Acts as an anchor holder and anchor lock to keep the line or chain controlled and off the hull. The nylon roller (42 x 63 mm) rotates to reduce wear on the lead and minimize noise and vibration. The 10 mm mounting hole allows secure bolting to boat structures. Important specifications Frame material: 304 stainless steel Roller material: nylon Roller dimensions: 42 x 63 mm Mounting hole diameter: 10 mm Function: anchor lock / anchor holder / roller guide Installation: holes included for easy mounting Practical use scenarios Small powerboat bow: mount the unit at the bow to guide the anchor line during anchoring and prevent the lead from scraping the hull during retrieval. Sailboat berth and mooring: install near the bow locker to keep chain or rope aligned while anchoring in variable currents. Docking and short-term anchoring: use as a fixed anchor holder to hold the anchor steady and reduce movement-related wear on the hull when anchored close to shore. Installation tips Use appropriate grade fasteners and backing plates for your boat’s construction material. Position the unit so the roller is aligned with the expected line path to minimize side loads. Inspect fastenings and roller condition periodically for safe operation. This part is intended as a direct anchor lock and roller replacement or upgrade for boat anchoring systems that accept a 42 x 63 mm nylon roller and a 10 mm mounting hole, with a 304 stainless steel frame for marine use.
