TWF Trench Boxes Type 100
Updated: 26.05.2026
The Trench Boxes Type 100 are mainly used for shallow trenches at inner city projects for laying small diameter utility lines such as water pipes, cable ducts, sewer house connections and equivalent. Four sizes of lightweight MINI spindles, which are fixed to the box plates by just two steel pins, allow a trench width from 660-3210 mm.
