Recommended Lid Weight & Installation Guidance
Force Rating: 100N per strut (200N total per pair)
Recommended Lid Weight: Suitable for lids approximately 5–18kg when using a pair of struts. (Actual performance depends on hinge position and mounting geometry.)
Recommended Mounting Position:
- Install one strut on each side of the lid.
- Mount approximately 20–30% down from the hinge on the lid panel.
- Fix the lower bracket around 80–120mm below the top edge of the box frame (depending on internal depth).
- Ensure the strut is slightly compressed when fully closed to maintain preload.
⚠ If the lid is heavier than 18kg, a higher force rating (e.g. 150N or 200N) may be required. If the lid is lighter than 5kg, the struts may feel too strong.

This kit includes 4x heavy-duty L brackets (90° angle brackets) and is recommended for:
-
Storage boxes with thick internal frames
