Which lifeline is mainly used as rigging rope in 20'-30' lengths?

• A. KM III Lifeline
• B. Static-Pro Lifeline
• C. CMC Lifeline
• D. Tag Line

Answer: (C)

The main idea here is that rigging rope is chosen for setting up anchors and moving loads, not for supporting a climber. For rigging, you want a line that is readily available in short, manageable lengths (around twenty to thirty feet), strong, and stable with good abrasion resistance. The CMC Lifeline fits that role well because it’s a general-purpose, static line that teams commonly stock for rigging tasks and can be cut or used in short segments without adding unnecessary stretch or complexity. This makes it the practical choice when the goal is a dependable rigging rope in 20–30 foot lengths. KM III Lifeline and Static-Pro Lifeline are typically selected for life-safety applications, emphasizing characteristics like specific elongation or dynamic behavior that aren’t ideal for routine rigging work. A Tag Line is a lighter line intended to guide or control loads, not to act as a lifeline or to bear the same rigging loads, so it isn’t the best fit for this purpose.
