Vepagoo 15 Inch Heavy Duty Soft Close Gas Struts (2 Pack)
Best for heavy boat hatches or storage lids where a soft-close action reduces slam. Each strut delivers 100N / 22.5 lb of lift, enabling reliable opening with one finger and smooth, controlled closing. The extended length is about 14.96 inches with a compressed length of 9.06 inches, fitting lids in the 18–25 lb range and 22–30 inches long. The universal L-bracket design provides 360° adjustability, supporting curved, round, flat, or angled surfaces. Choose this if you want strong, simple installation for very heavy lids and easy future adjustments.
Best for: boat hatch lockers and thick toolbox lids that experience frequent use and require controlled, quiet operation. Caution: ensure lid weight and length stay within the stated ranges to avoid over-extension.
Vepagoo 2 Pack Soft Close Gas Struts 15 Inch (67Lb / 300N)
This option offers higher lift capacity for moderately heavy boat hatches and storage lids, with 300N (67 lb) per strut. Extended length is 14.96 inches; compressed length 9.06 inches. It features a 360° rotatable ball-end bracket, making alignment easier on curved surfaces. Best for: lids that routinely approach heavier loads but still require smooth, controlled motion. Limitation: heavier struts may require more robust mounting hardware and careful alignment during installation.
ARANA 15 Inch 45lb with Brackets (2 Pack)
ARANA’s 15-inch, 45-pound gas struts provide balanced lift for lighter boat lids and storage boxes. They extend to about 14.96 inches and compress to 9.06 inches, with 360° adjustable L-brackets to fit varying mounting angles. Best for: DIY projects where a reliable, moderate lift is needed without overshooting. Caution: rated for lighter lids; ensure your lid does not exceed the 45 lb per strut specification.
AUCLIDIS 10 Inch 40Lb Gas Strut Set (2-Pack)
AUCLIDIS provides a shorter 10-inch variant with 40 lb lift per strut, suitable for smaller hatches or compact compartments on small boats or trailers. The set includes two gas struts and brackets with clear interchange information for matching OEM numbers. Best for: smaller lids or when a compact replacement is required. Limitation: shorter stroke means less lift range for very tall lids.
ARANA 20 Inch 100 Lb Heavy Duty Set
This pair targets very heavy lids, such as large boat hatches or RV doors. Each strut delivers 100 lb of lift, with an extended length near 19.69 inches and 11.82-inch compressed length. Brackets are included for straightforward mounting. Best for: heavy-duty lids that require significant supporting force and stable, non-slam operation. Caution: heavier force may require sturdier mounting points and professional install to prevent mounting hardware fatigue.
Euplokeer 20in 60lb (2 Pack) with Mounting Brackets
Euplokeer’s 20-inch, 60-pound struts are a middle-ground option for boat hatches that require longer reach with moderate lift. The set includes mounting brackets and covers compatibility with several interchange numbers to help with fit. Best for: longer lids needing consistent lift without excessive force. Limitation: ensure your lid weight remains within the 60 lb per strut specification.
Buying Guide
What should you consider when buying a boat hatch lift cylinder?
- Weight of the lid: Match the per-strut lift (lb or N) to the lid’s weight. For heavier lids, prefer 67–100 lb per strut; for lighter lids, 40–60 lb per strut may suffice.
- Length and stroke: Ensure extended and compressed lengths fit your mounting space. Longer strokes can require more clearance but provide smoother lifting trajectories.
- Mounting brackets: Look for rotatable ball ends or 360° brackets for easy alignment on curved or angled surfaces. Check whether brackets are included or must be purchased separately.
- Soft-close vs. standard lift: Soft-close designs reduce slam and control lowering speed, beneficial for cabin doors and boat hatches in marine environments.
- Durability: Marine applications benefit from corrosion-resistant materials and seals. Consider products with proven performance in outdoor, temperature-extreme conditions.
- Installation complexity: Some sets include brackets and screws; others require separate hardware. Review the part numbers to ensure compatibility with your existing cylinder.
Frequently Asked Questions
- How do I know which gas strut length to choose?
- Can I replace a gas strut on any hatch?
- What if my lid is heavier than the strut rating?
- Are soft-close gas struts necessary for boats?
- Do brackets affect mounting orientation?
- What maintenance is required?
Measure the extended length when the hatch is fully open and the compressed length when closed. Choose a strut whose extended length matches your required open position and whose compressed length fits the closed position without bottoming out.
Replacement depends on matching the stroke, force, mounting points, and ball joint size. Compare original part numbers and ensure the new strut’s ends and brackets fit your hinge geometry.
Using a strut with insufficient lift can cause stalling or failure to hold the lid. Upsize to a higher-capacity strut or use a pair of struts to distribute weight.
Soft-close struts are beneficial for preventing loud slams in wet environments and for protecting delicate equipment inside compartments.
Yes. Rotatable or 360° brackets offer flexible mounting angles, making installation easier on curved, flat, or angled surfaces.
Periodic inspection for oil leaks, corrosion resistance, and mounting hardware integrity helps ensure consistent performance and safety.
