Stock Box

Model: Bar‑M Stock Boxes

Not every livestock hauling job calls for a trailer. When you need a fast, dependable, and easy-to-use solution for transporting smaller loads, the Bar‑M Stock Box is built to get the job done.

Designed for daily farm, ranch, and show use, Bar‑M Stock Boxes combine rugged aluminum construction with practical livestock-handling features in a compact package that fits your truck and your operation. Durable construction, excellent ventilation, secure loading access, and easy maintenance make these units ideal for producers who need a reliable hauling solution without the size and complexity of a full trailer.

Built with a one-piece aluminum roof, fully encapsulated diamond plate floor, and full-height side slat construction, every Bar‑M Stock Box is engineered to withstand years of hard use while providing the airflow livestock need during transport. Available fold-down air gaps, roof vents, and optional center gating allow you to customize the unit to your operation and changing weather conditions.

Full-length side handles, sturdy rear doors, LED interior lighting, and marker lights make loading, unloading, and daily use simple and efficient. Available in multiple sizes, these stock boxes provide a versatile hauling solution whether you’re moving livestock across the farm, heading to the sale barn, transporting show animals, or making a quick trip down the road.

Compact, rugged, and built to work, the Bar‑M Stock Box delivers the durability, convenience, and reliability livestock owners depend on every day.
