Whitecap 20" Gas Spring - 120lb - Stainless Steel

The Whitecap 20" Gas Spring - 120lb - Stainless Steel (model G-34120SSC) is a marine-grade support strut engineered for hatches, enclosures, and equipment doors on boats and offshore vessels. This 316 stainless steel gas spring combines corrosion resistance with reliable force delivery in the harsh saltwater environment, making it essential hardware for serious boaters who demand longevity and dependable operation in demanding marine conditions.

The Whitecap gas spring features a 20-inch extended length that compresses to 12 inches, delivering 120 pounds of lifting force across its travel range. An 8mm rod diameter paired with an 18mm tube diameter provides the structural rigidity needed to support cabinet doors, hatch covers, and ventilation panels without sagging or drift over time. The 316 stainless steel construction resists salt spray, UV exposure, and moisture infiltration—critical advantages over painted steel or lower-grade alloys that corrode rapidly in marine service. This gas spring maintains consistent force output across temperature swings and repeated cycling, a characteristic boaters experience firsthand when opening and closing enclosures in changing weather.

Whitecap gas springs are specified by manufacturers of center consoles, cabin cruisers, and commercial fishing vessels. The 120-pound force rating suits applications where moderate support is needed—larger deck hatches, windlass enclosures, and engine compartment covers. Weekend anglers and full-time offshore operators alike depend on Whitecap struts to keep equipment accessible and secure without manual prop-open rods or improvised supports that fail under load. Replacement and upgrade installations benefit from the exact dimensional specs and proven track record of this model.
