Attwood SL34605 gas spring lift support is a 60 lb hatch/deck spring replacement designed for a 20" extended length and 12" compressed length (8" stroke), built for reliable marine hatch support.

Key Features

  • 20" extended length and 12" compressed length (8" stroke) for hatch support geometry
  • 60 lb output force for steady lift assistance
  • Marine-oriented corrosion resistance testing (ASTM B117 and salt spray) and a 30,000 cycle lifecycle test
  • Bio-degradable, no-hazard-to-water grade oil (WGK) for reduced environmental impact
  • Uses a socket-style end fitting (10mm) for attachment at compatible hatch hardware

Intended Use

  • Marine deck hatches and access ports (gas spring / lift support replacement)
  • RV and marine-style hatch supports that use compatible 20" extended, 12" compressed, ~8" stroke geometry
  • Applications requiring a 60 lb gas spring with 10mm socket-style end fittings

  • Compressed length: 12"
  • Stroke: 8"
  • Force (output): 60 lbs

Parts Desk Insights

Best Use Case: Best for replacing a worn or weak gas spring on a marine hatch/access port when you need a 20" extended / 12" compressed support with 60 lb force.

Common Issues: Most common fitment problems come from mismatched geometry (extended/compressed lengths) or end-fitting type. If the hatch height or bracket locations don’t match the needed stroke, the lift may feel weak or bind—verify dimensions against your hatch mounting points.
