Question

Quizplus · Accepted Answer

Rope grabs, also known as ascenders or jumars, are the devices designed to prevent a rope from slipping when ascending or hauling. They grip onto the rope tightly when loaded in one direction but can slide smoothly in the opposite direction. Carabiners are used for connecting components and anchors are used for providing a secure point to attach equipment. Pulleys are used to change direction or increase mechanical advantage in a hauling system but do not prevent the rope from slipping.
