Recommended Lid Weight & Installation Guidance
Force Output: 200N per strut (400N per pair)
Designed to assist heavier lids weighing approximately 20–36kg when mounted correctly. Actual lifting performance depends on hinge placement, lid material and installation geometry.
Recommended Mounting Setup:
- Install one strut on each side of the lid
- Fix the upper bracket approx. 20–30% down from the hinge
- Mount the lower bracket approx. 80–120mm below the top inner frame edge
- Ensure slight compression when the lid is fully closed to maintain preload tension
⚠ If lid weight exceeds 36kg, a higher force rating may be required.
⚠ For lids significantly lighter than 20kg, the struts may feel too strong.
🔧 Mounting Bracket Type – 2x L + 2x Flat Bracket Kit
This kit includes 2x heavy-duty L brackets (90° angle brackets) for the box side and 2x flat brackets for the lid side.
Recommended for:
- Standard patio storage boxes with reinforced lids
- Wooden chests and storage benches
- MDF or composite panel lid constructions
- Storage boxes with limited internal clearance
- Domestic and commercial deck box installations
The L brackets provide correct mounting offset on the box wall, while the flat brackets create a lower-profile pivot point on the lid for smoother articulation.
⚠️ For thick-framed lids or installations requiring additional pivot height, a full 4x L bracket kit may be more suitable.
💡 Not Sure Which to Choose?
If your box has a thick-framed lid or requires extra offset → choose 4x L Brackets.
If your lid is flat and standard construction → choose 2x L + 2x Flat Combination.
