Description

The Chain Locker Bonnet is a heavy-duty protective cover installed over the chain locker opening to safeguard anchor chain storage spaces from seawater, debris, and environmental exposure. Built from high-strength steel or marine-grade aluminum, it is engineered to withstand harsh marine conditions while providing a secure seal. The bonnet ensures crew safety by preventing accidental access during vessel operation and reducing the risk of corrosion or contamination inside the chain locker. Available in hinged, bolted, or quick-release designs, it can be customized to fit specific vessel layouts and classification society requirements.

It can be made with a cover and side flanges on one or more sides.

The cover can be hinged or removable to allow easy access to the chain locker.

It can be made of welded or cast pipe. The fittings are usually made of stainless steel.
