Sea-Dog Gas Filled Lift Spring - 20" - 90#

The Sea-Dog Gas Filled Lift Spring – 20" – 90# is a pneumatic support mechanism designed for equipment lids, hatches, deck access panels, and marine hardware that require controlled, assisted opening and closing. It is ideal for boat owners, RV enthusiasts, and mechanics who need to reduce manual strain while providing smooth and stable support across various ambient temperatures.

With a compressed length of 20 inches and a force rating of 90 pounds, this gas spring is perfect for medium-duty applications where reliable operation is essential. It operates using pressurized nitrogen sealed within a precision-engineered cylinder, which allows for upward force as the lid or panel is lifted. The durable chrome-plated steel construction and sealed components resist corrosion, salt spray, and UV exposure, making it suitable for marine and automotive environments.

This lift spring is compatible with various applications, including boat hatch covers, engine compartment lids, tonneau covers, and tool-box access panels. Its design ensures that it provides adequate support without over-assisting lighter lids or under-performing on heavier ones, making it a versatile choice for any hinged or sliding assembly requiring assisted opening.
