Aluminium Boxes Overview
- Aluminium Trench Boxes are most suitable for supporting trenches up to 1.5m* deep where the excavation is being undertaken with mini diggers or small excavators which have a limited lifting capacity.
- These lightweight boxes are ideal for smaller jobs in place of steel trench boxes.
- The boxes are fitted with a four-point lifting system for safe slinging.
- They are easily assembled and can be transported in a large van or pick up.
