Recommended Lid Weight & Installation Guidance
Force Rating: 400N per strut (800N total per pair)
Recommended Lid Weight: Works best for lids around 40–72kg with correct mounting geometry.
- Use one strut on each side of the lid.
- Upper fixing: roughly 20–30% down from the hinge on the lid.
- Lower fixing: about 90–150mm below the top inside frame edge.
- Maintain slight compression when fully closed for preload.
⚠ If the lid is heavier than 72kg, consider a higher force rating.
⚠ If the lid is lighter than 40kg, the struts may feel overly strong.
🔧 Mounting Bracket Type – 2x L + 2x Flat Kit
This mixed kit gives you the most flexible, low-profile installation for domestic patio boxes:
-
L brackets provide the correct offset on the box side wall
-
Flat brackets keep the lid mounting neat on flat panels
- Ideal when internal clearance is limited
Secure 10mm Ball Socket System
The ball-and-socket connection allows smooth movement throughout the opening arc, helping the lid lift evenly and reducing stress on hinges.
Smooth and Controlled Lid Support
With 800N combined force, the lid opens smoothly and closes in a controlled way to help prevent sudden drops.
