Buying Guide
- Load capacity: Choose a pair with total lift equal to or slightly above the lid weight. For heavy lids, presets around 100–150 lbs per set are common; for lighter lids, 24–30 lbs per strut may suffice.
- Length and stroke: Extended length should give full lid clearance; compressed length determines how compact the installed height will be. Ensure the stroke matches the required lift progression.
- Mounting style: Look for one-piece brackets for ease of installation or separate mounting plates if you need a custom fit. Confirm hole spacing for your mounting surface.
- Compatibility: Verify lid type (flip-up vs. lift-up) and lid weight range. Some products are universal; others require exact specifications for proper balance.
- Durability: Materials like steel hardware and corrosion-resistant finishes extend life in humid or coastal environments. Check warranty and testing standards (e.g., TÜV/NORD).
- Installation: Consider whether installation requires special tools. Some kits come with brackets and screws, while others need additional hardware.
- Noise and smoothness: Look for cushioning design and soft-closing behavior to minimize slams and noise during operation.
- Maintenance: Periodic inspection of mounting screws and alignment can prevent sagging and ensure consistent performance over time.
- Safety: Ensure proper load distribution and avoid overloading, which may damage hinges, lids, or the struts themselves.
