Which statement best describes edge transition in rigging?

• A. Moving rope to edge
• B. Moving rope from lower to higher plane while maintaining load control and protecting rope
• C. Lowering rope to ground
• D. Removing rope from system

Answer: (B)

Edge transition is about guiding a loaded rope as it passes over an edge, changing the rope’s path from a lower plane to a higher plane while keeping the load under control and protecting the rope from abrasion at the edge. This definition matches the choice that describes moving the rope from a lower plane to a higher plane while maintaining load control and protecting the rope, because it includes both the change in plane across the edge and the need to maintain control and rope protection throughout the transition. The other options don’t capture this combination: simply moving the rope to the edge doesn’t address the change in plane or load control; lowering the rope to the ground or removing the rope from the system aren’t about transitioning the rope across an edge under load.
