Is your boat hatch or compartment lid not staying up like it used to? This Sierra International gas spring is the exact OEM replacement you need. It's rated for 40 pounds of force, so it's strong enough to hold up those heavier hatches without slamming shut. The extended length is 7.5 inches, and it compresses down to 5.5 inches, so make sure that matches your old one before ordering. The steel rod is nitride-coated to fight off saltwater corrosion, and it's got bronze bushings and polymer rod ends for smooth operation. This isn't some generic part - it's engineered to fit right in place of your original, no modifications needed. Perfect for marine applications on cabin doors, engine hatches, storage compartments, or even some RV applications. Installation is usually pretty straightforward: just compress it, line up the ends, and pop it into place. Much better than propping things open with a stick, right? Get your boat back in proper working order with this reliable gas spring.
