A block and tackle rigged to the secondary line primarily provides which of the following to the line?

• A. Compression
• B. Tension
• C. Weight
• D. Lift

Answer: (B)

A block-and-tackle on the secondary line is used to apply a controlled pulling force that increases the line’s tension. The pulleys multiply your effort, allowing you to generate and adjust the tension more easily, which keeps the conductor taut between supports, controls sag, and helps with alignment during installation. It isn’t about compressing the line, adding weight, or lifting a load in this context—the primary effect is increasing the line tension.
