Which side of the J-Frame brake bar rack do the bars pivot on?

The bars of a J-Frame brake bar rack pivot on the long side. This design allows for better control and leverages the mechanical advantage during rope rescue operations. The long side provides a stable pivot point, which is essential for maintaining the alignment of the bars when they are being manipulated.

When the long side is used for pivoting, it also facilitates a smoother operation while feeding or taking in rope, as well as achieving controlled braking action during a descent. This arrangement is designed to enhance both safety and efficiency during rescues, ensuring that the personnel can manage their equipment effectively.

Understanding the mechanics of the J-Frame brake bar rack is crucial for utilizing it properly in rescue scenarios, where precise control can significantly impact the outcome of an operation.
