Parts Desk Insights
Best Use Case: Use this anchor lock when you want a fast, positive hold for your anchor shackle or chain on the bow roller—helpful for reducing the chance of accidental release while underway.
Common Issues: Check that your shackle/chain diameter matches the stated up-to 3/8" capacity, and confirm the lock is aligned so the 1/4" pin fully engages. Periodically inspect for corrosion, and verify mating surfaces remain clean so the pin seats securely.
