Which should you select first when using tackle blocks?

• A. Blocks
• B. Ropes
• C. Pulleys
• D. Knots

Answer: (A)

Selecting the blocks first defines the whole rigging arrangement. The blocks determine how many rope parts will support the load, the direction the rope will travel, and the overall mechanical advantage you’ll achieve. Once you know the block setup, you can choose a rope that fits the groove sizes and the required load capacity, and you can plan the length and routing of the line to complete a safe, functional system. If you start with the rope or other parts, you risk picking components that don’t fit the block configuration or don’t meet the required strength and path, making the setup unsafe or inefficient.
