Benefits of Using Gas Struts for Windows
Smooth Opening Control
Gas struts provide controlled and smooth window movement, helping prevent sudden opening or closing. They allow windows, hatches, and panels to move gradually and safely, improving user experience and reducing impact on the mounting structure.
Safe Position Holding
Gas struts securely hold windows at the desired opening angle, ensuring stable positioning during operation, inspection, or ventilation. This helps prevent unexpected movement caused by vibration, wind, or external forces.
Reduced Manual Effort
Gas struts assist with lifting and supporting window weight, making heavy panels easier to open and close. They reduce the physical effort required from operators and improve convenience in daily use.
Long Service Life
Designed with durable materials and reliable gas pressure performance, gas struts provide long-term operation in various environments. Properly selected gas struts help maintain consistent performance through repeated opening and closing cycles.

| RV / Caravan | 90° or fixed | Vibration & corrosion resistance | Nitro-carburized rod, SS 304/316 |
How to Specify the Right Gas Strut for Your Window Project?
When sourcing gas window struts, four parameters determine fit and performance
| Parameter | Why It Matters | Typical Window Range |
|---|---|---|
| Extended Length | Must match the mounting point distance when the sash is fully open | 200mm – 800mm for awning/pass-through |
| Force (Newtons) | Balances sash weight without overloading the frame | 100N – 800N depending on glass weight |
| End Fittings | Ball socket, eyelet, or clevis must match your window hardware | Ball socket common for RV & awning |
| Damping Type | Dynamic damping for smooth any-position stop; hydraulic for end-of-stroke soft close | Specify based on user experience goal |

Frequently Asked Questions
What are gas window struts used for?
Gas window struts are used to assist opening, support and control the movement of windows in vehicles, industrial equipment, marine applications and other systems.
Can gas window struts be customized?
Yes. Gas window struts can be customized according to force requirements, stroke length, mounting brackets, materials and installation conditions.
How do I choose the correct gas strut for a window?
Selection depends on window weight, opening angle, mounting position and required lifting force.
What materials are available for window gas struts?
Common materials include painted steel and stainless steel options for environments requiring corrosion resistance.
How do I choose the right force (Newton) for my window?
Force selection depends primarily on three factors: sash weight, mounting point geometry, and the angle at which you need the window to hold. A heavier sash or a mounting position with less mechanical advantage requires a higher Newton rating. For most pass-through and awning windows, forces fall in the 100N–800N range. We recommend sending your sash weight and mounting diagram — our team will calculate the correct force rather than guessing.
Can gas struts hold a window open at 90° without a lock?
Standard gas struts can hold a window at 90°, but holding force depends on the force curve and the load on the sash. For pass-through and servery windows where safety matters — for example, a busy restaurant counter — we recommend lockable or self-locking gas struts. These mechanically lock the sash in the open position so it cannot be pushed closed accidentally.
Are your gas struts suitable for outdoor and coastal window installations?
Yes. For outdoor-facing windows, high-humidity environments, and coastal or marine installations, we supply struts with nitro-carburized piston rods and stainless steel 304 or 316 cylinders and end fittings. These resist salt spray and corrosion far better than standard painted steel. Let us know your environment and we will specify the right material grade.
What temperature range can your window gas struts operate in?
Our RV-grade and outdoor window struts are tested for reliable operation from -30°C to +80°C. Force output remains stable across this range, which is important for windows that face direct sun, cold climates, or the temperature swings typical of RV and caravan use.
Do you offer lockable gas struts for pass-through windows?
Yes. We manufacture lockable and self-locking gas struts specifically for pass-through and servery window applications. The locking mechanism keeps the window fixed in the open position during food and drink service, preventing accidental closure. This is one of the most common requests from restaurant and hospitality fit-out contractors.
How do I know which end fitting works with my window hardware?
End fitting selection depends on your window frame and hinge design. The most common for window applications are ball socket, eyelet, and clevis fittings. If you send a photo or drawing of your mounting points, we will confirm the correct fitting type before production — this avoids the most common cause of installation failure.
