Outdoor Deck Box Gas Struts 250mm 200N – L & Flat Bracket Kit – Pair
✓ IN STOCK - SHIPS TODAY
Designed specifically for outdoor deck boxes and garden storage units, this 250mm 200N gas strut pair provides controlled, stable and weather-suitable lid assistance for medium-weight outdoor lids.
Unlike indoor chest struts, this configuration is optimised for deeper lid travel and outdoor exposure where wind, lid width and hinge leverage must be considered.

Built for Outdoor Geometry
Outdoor deck boxes typically feature wider and deeper lids than indoor chests. The 350mm extended length provides increased travel distance, allowing smooth opening on larger storage units.
- Improves control on wider outdoor lids
- Reduces sudden lid drop in windy conditions
- Supports reinforced plastic or timber panels
- Maintains steady hold-open positioning
The 200N rating delivers balanced lift assistance — strong enough for medium outdoor lids while maintaining smooth, natural movement.
L + Flat Bracket Configuration Explained
This combination kit is engineered for outdoor deck box layouts where:
- The chest wall requires angled mounting (L bracket)
- The lid underside is flat and benefits from a low-profile bracket
- Internal clearance space is limited
The L brackets create a correct offset from the box wall, while the flat brackets provide cleaner lid articulation compared to full 4x L bracket systems.
Installation Positioning Recommendations
- Install one strut per side
- Mount upper bracket approx. 20–30% down from the hinge line
- Place lower bracket approx. 90–130mm below the internal top frame
- Ensure slight compression when fully closed for correct preload tension
Correct positioning directly impacts lifting performance and long-term reliability.
Selecting the Right Force
- Lid below 20kg → this 200N set may feel firm
- Lid above 36kg → consider 300N option
- Lid depth beyond 500mm → consider longer 300mm configuration
Always calculate lid weight only (exclude contents).
