What is the term used for the bottom hole in a double pulley system?

The term used for the bottom hole in a double pulley system is known as a beckett. This hole is critical for the attachment of a rope or a load in various rigging configurations. It serves as a point where the rope can change direction, allowing mechanical advantages to be achieved through the pulley system. The beckett's design helps in seamlessly integrating the pulley into the overall system, ensuring efficient movement of the rope.

Understanding the role of a beckett is important, particularly in rescue scenarios where precise rigging is essential for safety and effectiveness. Knowledge of this part of the pulley system allows rescuers to properly configure their equipment for optimal performance, which can significantly impact the success of a rescue operation.

While the other terms listed, such as sheave, carabiner, and anchor, are integral components within the realm of rope systems, they refer to different elements. A sheave relates to the wheel within the pulley that the rope travels over; a carabiner is a type of connector used in climbing and rope work, and an anchor is a fixed point to which the system is secured. Each plays a specific role, but the beckett specifically indicates the bottom hole in a double pulley setup, making it the correct choice in this scenario
