Trench Boxes / Shields

In case of a trench collapse, a trench box (a type of trench shield) is designed to protect workers within the trench. Our trench box sizes range from 4 ft. by 8 ft. to 10 ft. by 24 ft., with up to a 6-in. wall thickness or knife-edge. Ideal for sewer and pipeline work, our steel trench shields feature double-walled construction for greater sidewall security and optimum strength-to-weight ratios. United Rentals trench experts are on hand to help you find the right trench boxes, shields or shoring for rent to fit your project and keep your employees safe at all times. For more information, one of our trench experts provides five key questions to ask yourself when deciding How to Choose the Right Trench Protective System.
