The Save-A-Load Cargo Bars incorporate an interior hydraulic cylinder pump, which keeps the bars secure against the walls of a trailer, even as the walls experience the normal flex and yaw common during road transport. The hydraulics also have a pressure-limiting valve, so that the operator cannot damage the trailer walls by over-extending the bars. Engineered for versatility and flexibility with lightweight materials, Save-A-Load Cargo bars offer an one-hand release mechanism. The company offers a variety of heavy duty bars, hoops and configurations. The products are available in various colors, and all are built so that parts are replaceable.
