Chain Extension 3/8in x 18.5in Hook and Oval

The MACS Custom Tie-Downs Chain Extension 3/8in x 18.5in with Hook and Oval is a heavy-duty marine-grade tow chain engineered for boat launching, trailer securing, and deck rigging. This 18.5-inch extension chain bridges gaps between anchor points and recovery equipment, offering the extra reach needed for safe tie-down and towing operations on the water. The 3/8-inch diameter provides substantial breaking strength while remaining manageable for single-hand deployment in wet conditions.

Built from cadmium-plated steel, this chain resists corrosion from prolonged salt-air and freshwater exposure—critical for marine equipment that endures constant moisture. The integrated grab hook allows quick connection to cleats, bitts, or other deck hardware, while the oval link design reduces kinking and distributes load evenly across the chain's length. The 2.8-pound weight keeps it portable for storage in tackle boxes, engine compartments, or emergency kits without adding significant deck clutter. At 5.5 x 2 x 6.25 inches when coiled, it stows compactly yet delivers the reach serious anglers and boat operators need for secure mooring and trailer launches.

This extension chain is ideal for weekend fishermen launching center-console boats at public ramps, as well as offshore anglers who run multiple anchor systems or need backup tethering during rough conditions. Charter captains and commercial operators rely on redundant tie-down systems to meet Coast Guard requirements and ensure crew safety. The grab hook design works with standard deck hardware—no specialized fittings required. Whether you're securing a trailer to a winch post, creating a backup anchor line, or extending reach to a distant cleat, this 3/8-inch marine chain extension combines proven cadmium-plated durability with practical, field-tested engineering.
