Attwood Stainless Steel Gas Spring ST34-80-5, 20 Inch, 80 lb Force, Hatch and Lid Support

The Attwood ST34-80-5 is a stainless steel gas spring designed to hold boat hatches, lids, and compartment doors open safely and smoothly. Gas springs like this one use a sealed, pressurized cylinder to provide consistent, controlled resistance, eliminating the need for prop rods or separate latches that can slip or fail. This model measures 20 inches and is rated at 80 pounds of force, making it suited for hatches and lids that need a firm, dependable lift assist.

Built in stainless steel, the ST34-80-5 resists corrosion in the marine environment, holding up to saltwater spray, humidity, and UV exposure better than painted or plated steel alternatives. It mounts using end fittings at each end of the cylinder rod and body, allowing the hatch or lid to swing open and stay in a raised position without the operator having to hold it manually. This makes it a practical replacement part for boat builders and owners maintaining storage compartments, engine hatches, console lids, and similar hinged panels aboard a boat.
