Maxwell Levered Chain Stopper f/5/16" or 8mm Chain

The Maxwell Levered Chain Stopper for 5/16" or 8mm chain is an essential deck fitting for cruising sailors, commercial fishermen, and serious boaters who demand reliable anchor handling. When you're working your ground tackle in heavy weather or holding position in challenging anchorages, this stopper prevents unwanted chain movement and protects your deck hardware from the constant stress of shifting loads. Built by Maxwell, a name trusted across the marine industry for over a century, this levered design gives you mechanical advantage and intuitive operation when you need it most.

This chain stopper uses a levered clamping mechanism specifically engineered for 5/16-inch or 8-millimeter anchor chain—the standard sizes found on vessels ranging from 30-foot cruisers to commercial workboats. The lever action provides mechanical advantage, allowing one person to secure or release the chain quickly without excessive force or complicated rigging. The stopper's compact footprint and straightforward installation make it a retrofit-friendly upgrade for existing deck layouts, while its all-stainless or marine-grade construction resists corrosion in saltwater environments.

Boaters who anchor regularly or fish from positions requiring steady ground tackle benefit most from this stopper's reliability and ease of use. Whether you're holding a fishing position in a river system, setting in a crowded anchorage, or managing charter operations where consistent performance matters, the Maxwell Levered Chain Stopper delivers predictable holding power without fidgeting or jury-rigging. Installation onto existing deck pad eyes or through-bolted mounts takes minutes, making this an affordable insurance policy against unexpected chain slip or fouled deck gear.
