What is the minimum diameter that rope can come into contact with?

• A. 8mm
• B. 10mm
• C. 14mm
• D. 12mm

Answer: (D)

When rope is in contact with a surface, edge, or device, the diameter determines how load is distributed at that contact point. A thinner rope concentrates force over a smaller area, increasing wear, risk of abrasion or cutting, and potential heat buildup where it runs over an edge or through hardware. To keep contact points safe and equipment reliable, there’s a practical minimum diameter that equipment and guidelines use. Twelve millimeters is that common lower bound because it provides enough thickness to resist edge damage and wear while still fitting typical hardware and devices. Ropes smaller than this are more prone to damage and grip issues at contact points, while ropes larger than this may be unnecessary for many setups. So the minimum diameter rope can come into contact with is twelve millimeters.
