Sea-Dog Gas Filled Lift Spring 60 lb, 17 Inch Extended Length, Marine and RV Gas Strut 321476-1

The Sea-Dog Gas Filled Lift Spring (part number 321476-1) is a 60 lb force gas strut built to marine OE standards for lifting and holding hatches, hoods, doors, and lids open. It extends to 17 inches with an 11 inch compressed length and a 6-3/4 inch stroke, giving it enough travel for a wide range of hatch and lid openings. The spring uses a 15 mm ball socket and a 6 mm pin, and is rated for both marine (Use 1) and RV (Use 2) applications.

Construction features a hard chromium plated shaft for corrosion resistance, bronze bushings for smooth long-term operation, and polymer end fittings that resist corrosion at the mounting points. A unique multi-lobe seal design gives the strut a longer service life and more consistent performance than typical gas springs, which is why Sea-Dog backs this Gas Filled Lift Spring with a 2-year warranty. It ships as a single unit and is intended for boat hatch, RV, truck cap, tool box, and utility applications where a self-supporting lift assist is needed.
