Vepagoo 20 Inch Stainless Gas Struts (60Lbs) For Boat Hatches
The two gas struts are designed for harsh environments and wet outdoor conditions, especially useful on boats, ships, and RVs. Each strut provides 60 lb of lift force, is built from 304 stainless steel to resist rust, and is suitable for direct replacement in compatible lids. Extended length is 19.69 inches with a 500 mm span, and each strut fits lids in the 48–66 lb weight range. Mounting hardware is not included, so verify your lid weight and OEM part numbers before purchase. Best for marine settings where corrosion resistance matters.
Who it’s for: boat owners needing durable, corrosion-resistant lift supports for engine compartments or hatch lids. Why selected: strong stainless build, reliable 60 lb load per strut, good for lids near the 50–60 lb range. Caution: mounting hardware not included; ensure your mounting points match the 10 mm end holes and required footprint.
ARANA 20 Inch 100 Lb Gas Struts (Two-Pack)
These 20-inch gas struts are designed for heavy lids and come with built-in mounting brackets on both ends for quick installation. Extended length is 19.69 inches with a compressed length of 11.82 inches and a stroke of 7.87 inches. They’re intended for lids up to roughly 60–110 pounds, making them a solid choice for RV beds, boat hatches, storage boxes, or basement doors. Best for: heavy-duty lids where safe, controlled lifting is essential. Caution: installation requires confirming lid weight and ensuring the included brackets fit your mounting points, as the unit has a built-in stand that cannot be removed.
Why chosen: robust 100 lb per strut capacity is ideal for relatively heavier lids while still providing smooth lifting action. Limitations: heavier units require sturdier mounting and may demand more precise alignment during installation.
Euplokeer 15in 50lb Gas Struts (Pair) With Brackets
Designed for 15-inch openings, these two 50 lb gas struts come with mounting brackets for straightforward installation. They’re a direct replacement for multiple OEM numbers and are suitable for RV storage doors, boat seat engine hatch lids, and similar smaller-lid applications. Best for: lighter engine hatches and compact compartments where a slim profile is beneficial. Caution: ensure OEM compatibility and original shock size before purchasing, as these are matched to 15-inch sizes and a 50 lb rating.
Why chosen: compact size fits smaller hatches, quick to install with included brackets, and suitable for common DIY boat and RV openings. Limitation: not ideal for heavy lids beyond 60 lb.
Euplokeer 20in 60lb Gas Struts (Pair) With Brackets
This 20-inch, 60 lb set is a direct replacement option with mounting brackets, suitable for boat engine hatches, RV doors, and certain camper shells. The kit includes two gas springs, two L-brackets, two flat-bottom brackets, and screws. Best for: moderately heavy lids in marine or RV contexts where a balance of lift and installation flexibility matters. Caution: check OEM numbers and ensure your lid weight aligns with the 60 lb per strut capacity to avoid over- or under- lifting.
Hurotoms 20″ 80Lbs Lift Struts (Pair)
Hurotoms offers a pair of 20-inch gas lift struts rated at 80 lb each, designed for heavier lids such as RV basements, boat hatches, or truck bed enclosures. Extended length is 19.7 inches, with a compressed length of 11.8 inches. Best for: lids in the 64–90 lb range where you need more lift than lighter sets but still want manageable installation. Caution: weight guidance is approximate; verify lid weight to avoid choosing too powerful a set which could cause abrupt opening.
Buying Guide
How to choose the right hatch lift
1) Measure the lid weight and opening height. Choose a lift with a force that slightly exceeds the lid weight for smooth, controlled opening. 2) Check the opening length and mounting footprint. Ensure the struts fit the hatch door without interference. 3) Consider corrosion resistance. Marine-grade stainless steel or zinc-coated parts perform better in saltwater or humid environments. 4) Verify OEM compatibility. Many products list interchangeable part numbers; match these to your existing hardware. 5) Review hardware inclusions. Some sets include mounting brackets and screws, others require separate hardware. 6) Decide on the number of struts. Heavier lids may need two struts for balanced support and safe operation.
Environment and application considerations
In marine applications, prioritize corrosion resistance and a secure hold at mid-opening angles. For RV or automotive use, ensure the mounting brackets fit standard chassis or box openings. If you operate in extreme temperatures, select units with seals and stainless components to prevent rust and stiffness.
Maintenance and safety tips
Regularly inspect hinges, brackets, and mounting screws for looseness. Clean tracks and pivot points to prevent buildup that could hinder movement. Test the lid’s opening angle and stopping points to ensure gradual, controlled motion, reducing the risk of injury or damage from sudden drops.
Quick compatibility checks
- Confirm the OEM part numbers or original gas shock size (length, force, and end fittings).
- Match the end fitting type (ball stud, pin, or specific mounting brackets).
- Measure the cylinder’s extended and compressed lengths to ensure proper fit in the installation cavity.
FAQ
- Q: Can I replace a gas strut with a different brand if the length matches? A: Yes, but ensure the force rating and mounting points are compatible to avoid over-stressing the hinge.
- Q: What happens if the lid is heavier than the strut rating? A: The lid will be difficult to lift, may stay closed, or cause the strut to fail over time.
- Q: Do I need professional installation? A: Basic DIY installation is common when measurements align and hardware is included, but professional help is advised for complex fixtures.
- Q: Are these suitable for marine-use only? A: Many are designed for marine environments, but compatibility with your specific hatch and mounting points is essential.
- Q: How do I know the mounting brackets fit my hatch? A: Compare the included bracket shapes and hole patterns with your existing hardware; confirm 10 mm hole diameters where applicable.
- Q: Do all sets include screws and brackets? A: Not always; review product descriptions to confirm what’s included before purchasing.
