What Are Trench Boxes?
Trench boxes are engineered steel or aluminum structures that are used to help protect workers who work inside trenches. These boxes are also known as sewer boxes, manhole boxes, trench shields, or tap boxes. Digging trenches is a necessary part of construction and engineering work. When digging for a building’s foundation, laying pipe or telephone lines, installing valves, or doing any number of underground jobs, trenches, and often trench boxes, are where the work is primarily done.
