• SpringLift stainless steel marine gas spring for hatch, lid, cover, and compartment support

• 40 lb force rating for moderate lift assistance
• 10 mm composite ball socket end fittings for secure mounting

Attwood stainless steel gas springs are built for marine hardware applications where corrosion resistance, smooth operation, and dependable support matter. This ST-Series gas spring features a stainless steel shell and rod, combined with high-strength corrosion-proof composite end fittings, making it a strong choice for hatches, covers, and compartments exposed to moisture, spray, and harsh boating conditions.

Built for Marine Environments

The stainless steel construction helps resist corrosion better than standard steel gas springs, making this model ideal for boats, docks, RVs, and other wet-environment applications. It is designed to replace an existing 15″ x 9.5″ ball-mount gas spring with a 40 lb pressure rating.

Ball Socket Mounting

The 10 mm composite ball socket end fittings are designed to attach to compatible 10 mm ball-stud mounting brackets. Mounting brackets are sold separately, so existing hardware should be checked for compatibility before installation.
