Sea-Dog Gas Lift Spring 321464-1, 40 lb, 15 Inch Extended Length, Marine and RV Hatch Support

The Sea-Dog Gas Lift Spring, part number 321464-1, is a gas-charged strut built to marine OE standards to hold hatches, doors, and covers open safely on boats and RVs. It provides 40 pounds of lift force, extending to a full 15 inches with a 9-1/2 inch compressed length, giving a 5-1/2 inch stroke of travel. The strut body is powder-coated steel for corrosion resistance, paired with a chrome-plated rod for smooth, repeatable extension and a clean finished look.

Mounting is via a 15 mm ball stud on one end and a 6 mm ball stud on the other, matching common marine and RV hatch, hood, and cover hardware. Because it is rated for both marine (1) and RV (2) use, it suits boat hatches, storage lids, console covers, and comparable RV lift-assist applications where a 40 lb, 15 inch gas spring is called for. Each unit ships individually as a single strut, ready to bolt onto existing ball studs or matching hardware.
