Attwood Marine Stainless Gas Spring, 10 in Extended, 60 lb, 10mm Socket

Overview

The Attwood Marine ST30-60-5 is a stainless gas spring for hatches, lids, and lockers on boats where moisture is part of normal use. It has a 10 inch extended length, a 7 inch compressed length, a 3 inch stroke, 10 mm socket ends, and 60 lb output force.

Use it where you need controlled lift support without taking up much room when the hatch is closed. The pressure tube and rod are stainless alloy, and the other exposed parts use stainless steel or marine-grade composite, which helps in compartments that stay wet and see salt exposure.

This spring is commonly used on livewells, line lockers, and deck hatches. Before replacing an existing unit, compare the length, force, and end fitting style with your current spring so the hatch opens through the right range and closes without binding.

Key features

• 10 inch extended length with 7 inch compressed length and 3 inch stroke for short-travel hatch and locker support
• 60 lb output force for lids and hatches that need steady lift assistance and hold-open support
• 10 mm socket end fittings for setups that use matching ball-stud style mounting points
• Stainless alloy pressure tube and rod for use in areas that stay damp and are exposed to saltwater
• Exposed components use stainless steel or marine-grade composite to suit livewells, line lockers, deck hatches, and similar compartments

Compatibility and fit

This gas spring is a good match when you are replacing another unit with the same 10 inch extended length, 7 inch compressed length, 10 mm socket ends, and a similar 60 lb force rating. On a boat, even small changes in spring length or force can affect how far a hatch opens and how much effort it takes to close.

Check the mounting point spacing with the hatch open and closed, and confirm that the spring force suits the weight and leverage of the lid. Matching the fitting style matters just as much as matching the force.

Installation and use

The 10 mm socket ends keep installation straightforward when the existing hardware uses the same connection style. If your current spring uses a different end fitting or a different travel range, the spring may not seat correctly through its full motion.

This type of support works well on fishing boats, center consoles, and cruising boats where wet storage compartments are opened often and need a clean, controlled lift. It is especially useful where a plain steel spring would corrode quickly.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
