TriTuff® 600 Circular Pit System

The TriTuff® pit and cover system was designed specifically to improve productivity at the work site by providing a lightweight but strong engineered product to Class B Loading.  Over three years in the development, Tri Underground have developed a breakthrough solution using a composite of the latest highly engineered plastic composites and steel to achieve the strength of an equivalent full steel cover and cast iron collar.  This system allows for a one man installation and ease of loading/unloading.trituff_pit_combo
