3” Aluminum Trench Shield
These aluminum panel trench shields are designed specifically for municipalities, and contractors who use rubber-tired backhoes or smaller excavators for trenching. Aluminum shields are made of lightweight, smooth, double-wall aluminum. Each 3-inch side-wall is constructed of foam-filled, 8 inch extrusions which prevent dirt build-up and reduces friction.
