What phrase is commonly used when a rope passes through a block?

When a rope passes through a block, the phrase "line in, line out" is commonly used. This terminology reflects the direction of the rope as it's being manipulated around the block. The phrase indicates how the rope is managed during lifting or pulling operations.

Understanding this phrase is vital in rigging to ensure clear communication among team members. When someone says "line in," it typically means that the rope is being pulled into the block, adding tension or lifting load. Conversely, "line out" indicates that the rope is being released or let out, which would decrease tension or lower the load.

This clarification helps maintain control and safety during rigging operations, ensuring everyone involved understands the movement of the rope and its implications on the load being managed. Other options do not express the specific action related to the interaction between the rope and the block as accurately.
