4-Sided-Manhole-Box_1

Conventional steel trench shields are a rugged protective system designed to ensure worker safety should a cave-in occur.

Steel Trench Box Shields

We have a complete inventory of trench boxes ranging from lightweight boxes for utility and general maintenance, to large boxes in 4, 6, and 8 inch thick walls designed for the deepest toughest projects. The trench boxes are built with high-strength steel. Four lifting points are built into the sidewalls with pulling eyes. They are adjustable and stackable. The compressed wood in the top horizontal limits bucket damage. The bottom is horizontally protected by a steel drag plate.
