How to Calculate and Measure Camper Gas Struts

To correctly calculate and measure camper gas struts, you must understand three key factors: the right length, the correct force in Newtons, and the ideal installation orientation.
These determine how smoothly your camper hatch or roof opens, stays, and closes.

This guide gives engineers, DIY users, and procurement managers a clear, step-by-step process —
from measuring extended length to calculating gas force, checking mounting position, and even selecting retail-ready models from the Gastac Shop. By following these principles, you can achieve both precise fit and long-term reliability.

Camper gas struts — also called camper trailer gas struts — are nitrogen-filled lifting supports used in camper roofs, doors, and hatches. Each gastac gas spring is engineered for smooth, damped movement and consistent load support.

As a certified gas springs manufacturer under ISO 9001:2015 and IATF 16949, Gastac guarantees automotive-grade reliability. Since 2007, we’ve offered OEM customization, bulk procurement support, and stable quality with cost advantage across global markets.

Measuring correctly ensures proper opening angle and stability.
Follow these steps for both camper gas struts and camper trailer gas struts:

1. Extended Length – Measure from eye center to eye center when fully extended (≈ 60% of door height).

2. Stroke Length – Subtract closed length from extended length. Typical range: 300–600 mm.

3. Orientation – Mount with rod facing downward when closed to keep seals lubricated and extend lifespan.

To find the correct pressure for camper gas struts or camper trailer gas struts, use this simple formula:

Force (N) = Door Weight (kg) × 10 × Leverage Factor (0.6–0.8)

For example:
A 20 kg hatch × 10 × 0.7 = 140 N per strut → use two 140 N struts = 280 N total support. Always round up slightly to maintain safety margin and test physically.

Example for a camper trailer gas strut:

• Hatch height: 600 mm → strut length ≈ 360 mm (60%)

• Hatch weight: 25 kg

• 25 × 10 × 0.7 = 175 N per strut

Result: Two 175 N / 360 mm gastac gas struts ensure smooth lift and balanced motion.

As a global gas springs supplier since 2007, Gastac integrates IATF 16949 automotive process control with ISO 9001:2015 quality assurance.

• Bulk / Wholesale procurement support

• Stable quality with cost advantage

• OEM customization flexibility

Each gastac gas spring is cycle-tested for consistent pressure, corrosion resistance, and long-term reliability.

While many global brands mark up heavily, Gastac’s factory-direct model delivers IATF 16949-level quality at up to 30–50% lower cost.
For bulk procurement, this translates to faster ROI and system cost savings.

Automotive-grade quality at a factory-direct price.

By accurately calculating and measuring camper gas struts and camper trailer gas struts,
you ensure safer, smoother operation and extended service life.
