When your trenching operation demands reliability, Bear Iron Works delivers. Our high-performance Excavation Bedding Boxes—also known as Stone Boats, Gravel Boxes, and Dirt Boxes—are engineered for efficiency, durability, and real-world abuse. Whether you’re laying pipe, managing utility installs, or prepping for backfill, we’ve got the solution.

What Is a Bedding Box?

A Bedding Material Box is a heavy-duty container used to transport and contain bedding aggregate along a trench. These boxes—also called Utility Bedding Boxes, Pipe Bedding Boxes, or Construction Bedding Boxes—help minimize waste and maximize material placement efficiency.

Just attach the drag bar and pull the box alongside the trench. Operators can quickly access bedding material right where it's needed without excess spillage or lost time.
