What is a repel rack also known as?

A repel rack is commonly known as a brake bar rack because it utilizes a series of bars and friction devices that allow a rescuer to control their descent while rappelling. These bars create friction against the rope, providing the necessary braking action to slow down or stop the descent. This mechanism is crucial in rescue operations, where precise control over the speed of descent is vital for the safety of the person rappelling and the individuals involved in the rescue. The term "brake bar rack" highlights its function of providing braking capability in a controlled manner.

The other terms listed do not accurately describe the device or its primary function. For example, a regulator bar typically refers to a different mechanism used for various types of equipment, while a speed control device may apply to a broader range of tools without specifically indicating the robust capabilities of a brake bar rack. A descending module also implies a different design and application context than that of a traditional brake bar rack.
