Question 2130 Deck General

The correct answer is D) three times the circumference of a manila line. The cheek length of a block should be approximately three times the circumference of the manila line that will be used with the block. This guideline helps ensure the block is properly sized to accommodate the line and provide sufficient strength and durability. The other answer choices are incorrect because: A) twice the diameter is not the appropriate relationship, B) twenty times the diameter is excessive, and C) five times the diameter does not match the typical industry standard of three times the circumference.
