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.
