Trident Roto-Molded LPG Cylinder Locker – Single 20 lb
A complete, self-contained propane storage and control system for boats running a single cylinder. This roto-molded locker from Trident houses one 20 lb steel cylinder (or 17 lb composite cylinder) in a UV-protected polymer enclosure built to handle the marine environment. The double-walled lid, stainless steel hardware, foam seal, and durable latching system keep moisture and fumes contained — meeting the requirements for a safe, compliant onboard propane installation.
Everything needed to connect and control your propane supply is included. LPG cylinder sold separately.

Parts Desk Insights
Best suited for day boats, weekenders, and smaller cruisers where a single propane cylinder is sufficient for the galley or cockpit grill. The integrated solenoid valve and control panel let you shut off propane remotely from inside the boat — an important safety feature for any enclosed or semi-enclosed installation. If your propane needs are larger or you run extended passages, consider stepping up to the Trident Dual 20 lb LPG Cylinder Locker.
