ARANA Stainless Steel Gas Struts 20 Inch 80 Lbs
Best for moderate to heavy boat hatch lids that require reliable marine-grade support. These struts use 304 stainless steel to resist seawater corrosion and high temperatures, making them well-suited for wet marine environments. Extended length is 19.7 inches with a 11.8 inch compressed length, providing strong lift without excessive sag. Interchange numbers include 71794 and np1970-80, supporting a variety of compatible mounting configurations.
- Best for: Marine boat hatches and outdoor lids exposed to saltwater or splash.
- Why selected: Stainless steel construction offers corrosion resistance and durable performance in harsh environments.
- Caution: Ensure lid weight matches or stays within recommended 80 Lb per shock to avoid under- or over-pressurization.
C1608054 20″ Gas Prop Spring Strut 100 Lb
Best for heavy lids that need robust support with clear weight guidance. This ARANA set is specified for lid ranges around 85–110 lbs and provides a 19.7 inch extended length with an 11.8 inch compressed length. It is marketed as a direct replacement for heavy-duty applications like RV beds, tonneau covers, and boat lids, with multiple interchange numbers to aid compatibility.
- Best for: Heavier lids around 85–110 lbs; RV, trailer, and marine applications.
- Why selected: Explicit guidance on lid weight helps prevent wrong purchases and ensures proper support.
- Caution: Package note indicates mounting hardware may be required separately for some setups.
ARANA Gas Struts 20 inch 150LB
Best for very heavy lids and multi-purpose use across vehicles and boats. These 20-inch struts are designed for lid weights between 150–210 lbs, suitable for heavy boat lids, under-bed compartments, truck beds, and large tonneau covers. They are marketed as direct replacements with multiple OEM interchange numbers like C16-17566 and lgp8-200-150, indicating broad compatibility.
- Best for: Very heavy lids and multi-scenario usage around boats and trucks.
- Why selected: Higher 150 lb capacity expands use cases beyond standard marine hatch lifts.
- Caution: Verify lid weight and mounting compatibility before purchase to avoid mismatches.
AUCLIDIS C16-18233 10 Inch 40Lb
Best for smaller or lighter lids, such as toolbox covers, boat hatches with modest weight, or cabinet doors. This AUCLIDIS model is a 10-inch strut with 40 lb capacity, designed for replacement parts and compatibility with a wide range of OEM numbers, including C16-18233 and 40231540. It’s important to match the original OEM number for proper fit.
- Best for: Light to moderate lids in boats, toolboxes, or cabinets.
- Why selected: Wide interchanges increase the chance of finding a compatible fit.
- Caution: Lower lift capacity means not suitable for heavier lids; verify lid weight before purchase.
Buying Guide
Key purchase considerations guide you to the right gas strut for a boat hatch:
- Load capacity: Match the strut’s pounds or Newtons to the lid weight. Underestimating capacity leads to insufficient lift, while overestimating can wear components faster.
- Length and stroke: Measure the extended and compressed lengths to ensure proper fit and range of motion for hatch openings.
- Material and environment: Choose corrosion-resistant materials (stainless steel) for marine environments and temperature endurance for outdoor use.
- Mounting hardware availability: Some products specify separate mounting brackets or hardware; confirm what is included or needs to be purchased separately.
- OEM compatibility: Check interchange numbers or OEM references to maximize the chance of a precise replacement.
- Usage scenario: Consider whether the lid is frequently opened and closed, and whether you need lightweight or heavy-duty support.
Frequently Asked Questions
- What load capacity should I choose for a boat hatch?
Choose a strut with a lift capacity that matches or slightly exceeds the lid weight to ensure smooth operation without overloading the shock. - Can I replace a gas strut without tools?
Most replacements require basic mounting hardware and simple tools; always follow manufacturer guidance for safe installation. - Are marine-grade struts necessary for boat hatches?
Yes, marine-grade stainless steel or corrosion-resistant variants provide longer life in saltwater and wet environments. - How do I verify compatibility with my hatch?
Compare extended length, compressed length, and OEM interchange numbers to your current struts or lid specifications. - What if my lid is heavier than the strut rating?
Avoid this by selecting a higher-capacity model or consulting a professional for a custom solution. - Do all gas struts pause or slow during closing?
Some models offer soft-close features; most standard struts provide steady resistance without a dedicated soft-close mechanism.
