Sea Dog 304 Stainless Steel Chain Stopper – 3/16" to 1/4" Chain
Keep your anchor secure and your windlass protected with this formed 304 stainless steel chain stopper from Sea Dog. Sized for lighter 3/16" to 1/4" chain, it’s well-suited for smaller boats and pontoons running compact windlass systems. By locking the chain in place at rest, it takes the sustained load off your windlass — exactly the kind of static tension that windlasses aren’t designed to hold for extended periods.
Compatible Applications
- Fits anchor chain sizes 3/16" to 1/4"
- Mounts alone or inside most bow rollers
- Works in conjunction with your existing anchor roller setup
- Suited for smaller boats and pontoons with lighter anchor chain
Key Features
- Formed 304 stainless steel construction for strength and corrosion resistance
- Prevents accidental anchor free-fall while underway
- Protects windlass from high static loads it wasn’t designed to bear
- Compact size for lighter chain applications
- Mounts independently or inside most bow rollers
Parts Desk Insights
This is the smaller of the two Sea Dog chain stopper sizes — the right choice for boats running 3/16" or 1/4" chain, which is common on pontoons, smaller runabouts, and compact windlass setups. If you’re running heavier 5/16" or 3/8" chain, see the Sea Dog Chain Stopper for 5/16"–3/8" Chain instead. A chain stopper is one of the most overlooked windlass accessories — without one, your windlass bears the full static load of the rode at anchor, which accelerates wear on the motor and gypsy over time. Pair this with a SeaDog Anchor Swivel for a complete, well-protected anchoring setup.
