🌿 Designed for Outdoor Storage Systems
Unlike workshop or industrial gas springs, this configuration is tailored for outdoor deck boxes and garden storage units where:
- Lids are wider and front-loaded
- Wind can affect opening behaviour
- Controlled closing is important for safety
- Cushions, tools or garden accessories add weight
The 200N rating provides strong but balanced lift assistance — preventing sudden drops while maintaining smooth, natural movement.
🔩 4x L Bracket Mounting System
This kit includes four reinforced 90° L brackets, offering:
- Improved mounting stability inside plastic or composite deck boxes
- Better offset alignment for thicker lid frames
- Increased strength compared to flat bracket-only systems
- Secure load distribution across mounting points
Recommended for outdoor storage boxes with internal ribbing, moulded plastic frames or reinforced timber structures.
🛠 Installation Positioning Guide
- Install one strut on each side of the lid
- Mount approximately 25% down from the hinge on the lid panel
- Position lower bracket 80–120mm below top inside frame (depending on box depth)
- Ensure slight compression when fully closed for correct preload tension
Correct geometry is essential for optimal lifting performance. Improper placement may reduce lifting efficiency.
⚠ Choosing the Correct Strength
- If your lid weighs less than 20kg → 200N may feel too strong
- If your lid exceeds 36kg → consider 300N or 400N options
- If your lid depth exceeds 600mm → consider a longer strut length (e.g., 350mm)
Always calculate lid weight without contents. This rating applies to the lid panel only.
