Whitecap 20" Gas Spring - 40lb - Stainless Steel

The Whitecap 20" Gas Spring - 40lb - Stainless Steel is a marine-grade hydraulic support system designed for boat hatches, engine covers, hardtops, and cabin doors where controlled opening and closing are essential. After years on the water, any serious boater knows that heavy-duty hardware must withstand saltwater corrosion while delivering reliable performance in challenging marine environments. This gas spring provides constant, smooth assistance for heavy panels and lids, eliminating the need for manual props or dangerous unsupported openings.

Manufactured from 316 stainless steel—the same corrosion-resistant alloy used in offshore applications—this Whitecap gas spring features a 5mm rod diameter and 15mm tube diameter engineered for durability and longevity. The unit extends to a full 20 inches and compresses to 12 inches, with a 40-pound force rating (P1 Force) that provides consistent lift and support across the entire stroke. Stainless steel construction resists rust and pitting caused by saltwater spray and moisture exposure, ensuring years of maintenance-free operation without the degradation that plague standard steel springs.

This gas spring is ideal for installing or upgrading boat hardware on vessels of all sizes—from center consoles and cuddy cabins to larger cruisers and commercial vessels. The 40-pound force rating suits panels weighing approximately 40–60 pounds; for heavier applications, multiple springs can be installed side-by-side. Installation requires simple mounting brackets at both the panel and frame, with the spring positioned to open and close vertically or at slight angles. When ordering replacements or upgrading existing hardware, verify your panel weight and mounting span to ensure proper force rating and extended length compatibility.
