3L Trench Box


3L Trench Box

The 3” wall series of trench boxes are designed by GME with plumbing, utility and municipality workers in mind. These shields are lightweight and provide protection for the shallow depths required for light-duty repair work. This series of trench shields are ideal for rubber tired back hoes and excavators up to 30,000 lb.


The 3L Trench Box is specifically designed for plumbing and utility work, general maintenance, repairs, and other light duty applications. The 3L Series is easily handled by smaller rubber-tired backhoes, and lowered into position in the trench for fast worker protection and code compliance.
