Euplokeer GSNI-5150-50 15in 50lb Set
Best for smaller lids or lighter boat hatch covers. This 15-inch gas strut pair delivers approximately 50 pounds of lift force per unit, suitable for compact engine hatches or RV storage doors. The kit includes two gas springs, two L-brackets, bottom brackets, and screws for straightforward mounting. It supports a direct replacement for several OEM numbers such as GSNI-5150-50 and SPD-GS-5150-50, enabling a smoother lift without sudden drops. Caution: verify your lid weight and OEM part numbers to ensure compatibility. Better for lighter lids; may require larger strength struts for heavier heavy lids.
Who it’s best for: DIY enthusiasts replacing light-to-medium lids on small boats or RV compartments. This option is also approachable for beginners due to included mounting hardware.
Vepagoo C1608260 20 In 60Lb Gas Struts (Pair)
These 20-inch struts each provide about 60 pounds of lift, suitable for mid-weight lids like boat engine covers or RV hatch doors. Made from 304 stainless steel, they resist rust and seawater, extending lifespan in marine environments. The set does not include mounting hardware, so you’ll need to source brackets and screws separately. Best for: boats or RVs exposed to saltwater or humid conditions where corrosion resistance matters. Limitation: confirm mounting hardware compatibility with your lid before purchase.
ARANA 20 Inch 100 Lb Gas Struts
Best for heavy lids that require substantial lift without struggle. These 20-inch struts deliver around 100 pounds per unit and are designed as a one-piece bracket system for quick installation. The product notes emphasize suitability for RV beds, boat hatches, and heavy storage doors. Caution: installation may be more complex due to higher force; ensure safe mounting and lid alignment. Choose this if your lid weight approaches the upper end of typical marine or RV lids.
ARANA 304 Stainless Steel 20 Inch 100 Lb
Best for saltwater or high-humidity environments where corrosion resistance matters. This ARANA model uses 304 marine-grade stainless steel to resist rust while delivering robust lift for heavy lids like boat hatches or outdoor storage compartments. Extended length around 20.55 inches and compression around 12.13 inches help maintain controlled motion and secure positioning. Limitation: higher material cost; ensure lid weight is within the 80-110 lb working range for safe operation.
AiYiGu 20 Inch 100LB Gas Strut
Best for heavier lids in DIY projects or professional rebuilds. Each shock provides about 100 pounds of lift, suitable for lids in the 85-110 lb range, and includes mounting brackets for simpler installation. The product notes indicate easy installation using common tools. Caution: ensure your lid weight and mounting hardware compatibility are matched to avoid under- or over-tensioning the lift.
Buying Guide: Key Considerations For Choosing Hydraulic Hatch Lifts
- Weight compatibility: Match the lid weight (per-side or total) to the lift force (lb) of the strut set. Underestimating force can cause slow or unsafe opening; overestimating can stress hinges and brackets.
- Stroke and length: Ensure the extended length fits the lid clearance range when open and closed. Consider whether the mounting brackets align with existing holes and hinge geometry.
- Material and environment: For boats and coastal use, choose stainless steel (304 or higher) to resist saltwater corrosion. For dry environments, standard steel or coated options may suffice.
- Brackets and hardware: Some sets include mounting brackets and screws; others require separate hardware. Confirm compatibility with your lid’s mounting pattern (hole spacing, stud size).
- Installation complexity: Heavier lids may require two lifts and proper alignment to avoid lid tilting or sudden drops. Some models feature one-piece brackets for easier installation; others offer more flexible mounting options.
- Compatibility checks: Compare OEM part numbers or documented interchange numbers to avoid mismatches. If in doubt, measure lid weight, length, and hinge geometry before purchasing.
FAQ
- Q: How do I know which gas strut size to choose for my boat hatch?
A: Measure the lid length, approximate weight, and desired opening angle. Compare with the strut’s extended length and lift force (lb) to ensure safe operation. - Q: Can I use any universal gas strut for a boat hatch?
A: Not always. Compatibility depends on OEM part numbers, mounting bracket fit, and the lid’s weight. Check the specified interchange numbers and mounting hardware compatibility. - Q: Do these sets include mounting hardware?
A: Some sets include brackets and screws; others require additional hardware. Read product descriptions carefully to confirm. - Q: Are stainless steel struts necessary for marine use?
A: For saltwater or high-humidity environments, stainless steel (304 or higher) provides better corrosion resistance and longer service life. - Q: What if my lid is heavier than the listed range?
A: Choose a higher-capacity strut or use multiple struts, ensuring balanced lift and proper mounting to prevent lid drop or misalignment. - Q: How long does installation typically take?
A: For standard two-bracket sets with pre-drilled holes, installation can be completed within 30 minutes using common tools.
