The function of the anchor loops and ridge rail is to form an anchor point for personal fall protection. The ridge rail is used on pitched roofs; on low-pitched roofs (pitches of less than 6 degrees) with asphalt or artificial material-based sealing surfaces, anchor loops are used.
Most often, roof safety is used that fills several functions, such a walkways and snow fences, which also serve as anchor points. For solutions for these and more anchoring possibilities, see the CWL Safety System.
