Steel cable suspension systems are simple to install and relatively inexpensive. They are categorized by the number of suspension rows: single-row, double-row, and multi-row.
Single-row steel cable suspension systems are generally used in locations with small pipe diameters or poor ventilation where aesthetics are not a primary concern. Single-row systems are very simple and practical, typically oriented at the 12 o'clock position.
Double-row steel cable suspension systems are generally suitable for locations with larger pipe diameters. In the absence of ventilation, duct sagging can affect the area below the pipe. Double-row steel cable suspension systems are the most common installation method, with common installation orientations being 2 o'clock, 10 o'clock, 3 o'clock, and 9 o'clock.
Multi-row steel cable suspension systems are generally suitable for locations with larger duct diameters where aesthetics are a priority.
