The square manhole configuration provides ample inside clearance while reducing the area of excavation and restoration required. Shields are available in single or double walled models and are certified by a Registered Professional Engineer to meet OSHA standards. Features include: • Reinforced top rails • Thru wall lifting lugs and collars • Four-point lift system • Pinned spreader connections • Strongest knife edge in the industry
