Force Rating: 200N per strut (400N total per pair)
Recommended Lid Weight: Suitable for lids approximately 30–54kg when using a pair of struts.
(Actual performance depends on hinge position, lid material, 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 correct preload tension.
⚠ If the lid is heavier than 54kg, a higher force rating may be required.
⚠ If the lid is lighter than 30kg, the struts may feel too strong and push the lid upward.
