⚠️ Crucial Safety Note for Catenary Systems
- The "Zero Sag" Myth: It is physically impossible to have a perfectly flat catenary cable. Attempting to pull a cable completely straight requires infinite tension and will break the cable, pull out the anchors, or damage the walls.
- The 10% Rule of Thumb: For general installations (like festive lighting), aiming for a sag equal to roughly 2% to 5% of the total span length provides an excellent balance between a clean visual line and manageable structural tension.
