The TuffTech Aluminium Lower Trench Shield (TT-100) has been engineered as a lightweight, high-capacity solution for extra demanding excavation work. Built from high strength aluminium, it combines strength & durability with portability to deliver premium site performance while maintaining practical value.
Designed for an extensive range of projects, the TuffTech Aluminium Lower Shield (TT-100) combines strength with less system weight to make transport and positioning more manageable on site.
It can be used as a standalone trench shield or paired with the compatible TT-100 Upper Shield where additional protection height is required, giving contractors greater flexibility across changing excavation requirements.

High-strength aluminium construction delivers strong, durable trench protection at a significantly lower overall weight relative to other materials. This helps streamline transport and handling while still providing the strength and capacity required for tough work conditions.
A fully sealed working face creates a solid barrier between the excavation and the work area. The robust panel construction is designed for reliable performance across repeated site use, letting you maintain a practical and dependable trenching setup for multiple projects.
Twin extraction hook points provide a combined 42-tonne extraction capacity, giving crews a robust connection point when removing or repositioning the shield.
The TT-100 system is designed for straightforward assembly, helping reduce setup complexity on site.
A cutting edge on the lower panels helps the shield move more effectively and efficiently into position during installation.
An optional leading-edge cutting configuration can improve drag-box performance where the shield needs to advance through the trench as work continues. This provides added flexibility for specific working methods and site conditions.
