TWF Trench Boxes Type 300
Updated: 26.05.2026
The Trench Boxes Type 300 are used for medium size projects and are a combination of light box plates of 60 mm thickness but with our Type 600, heavy duty spindle system which is also used in our Type 600 trench boxes. Consequently trenches of 980-3760 mm inner width can be supported with maximum safety and efficiency.
