A block in rigging is defined as which of the following?

• A. One or more pulleys or sheaves confined in a wood or metal frame
• B. A knot tied around a rope
• C. A single wheel with no frame
• D. A fixed anchor point

Answer: (A)

In rigging, a block is a pulley assembly confined in a wood or metal frame. The frame keeps one or more pulleys (sheaves) aligned and securely housed, creating a movable unit that rope can run around and that can be attached to other rigging components. This setup is what defines a block and enables the use of block-and-tackle systems to change direction of pull and provide mechanical advantage. The other options don’t fit: a knot is simply a rope technique, a single wheel without a frame isn’t a block, and a fixed anchor point is just a stationary attachment, not a pulley assembly.
