Which of the following best describes the knot used on the power pole?

• A. oversized bolin on a bight
• B. slip knot
• C. round turn with a hitch
• D. fisherman's knot

Answer: (A)

When securing a rope around a round object like a power pole, the goal is to create a sturdy, adjustable loop that grips the pole under load and remains easy to release once the force is removed. The oversized bolin on a bight accomplishes this by forming a large, fixed loop around the pole using a bight, then locking the rope to itself in a way that distributes tension across the loop. This design minimizes sharp bends and point loading, helps prevent slipping, and stays relatively easy to untie after the load is gone.

This type of knot is preferred over a slip knot because slip knots tend to tighten or slip under tension, which can be unpredictable and unsafe when the rope is bearing weight around a pole. It’s also more reliable than a round turn with a hitch, which can jam or be harder to untie after it’s loaded for a while. A fisherman's knot isn’t suited here either, since it’s meant for joining two ropes, not for creating a secure, load-bearing connection around a cylindrical object.
