Product Details

The Sea-Dog Line 321489-1 is a gas-filled lift spring designed to provide smooth, controlled assistance for hatches, lids, engine covers, and access panels on boats and marine applications. This nitrogen gas-charged strut delivers 90 pounds of lifting force with a 20-inch extended length, making it ideal for medium to heavy-duty marine hardware applications.

Key Features:

  • 90 lb lifting force provides reliable support for hatches and compartment lids
  • 20-inch extended length for versatile installation options
  • Nitrogen gas-filled design ensures consistent, smooth operation
  • Marine-grade construction resists corrosion in harsh saltwater environments
  • Sealed design prevents gas leakage and maintains pressure over time
  • Easy bolt-on installation with standard mounting hardware

Gas lift springs are essential components for safe and convenient access to storage compartments, engine bays, and other enclosed areas on boats. The controlled damping action prevents hatches from slamming shut while providing enough force to hold them open securely. Sea-Dog Line's marine-grade construction ensures long-lasting performance even in demanding saltwater conditions.
