Which type of D-ring is intended solely for the attachment of connecting devices?

The positioning side D-ring is specifically designed for the attachment of connecting devices, particularly in fall protection systems. This type of D-ring is usually located on the side of a harness and is typically used for work positioning, allowing the user to secure themselves while working at height.

Its unique location and function differentiate it from other types of D-rings, such as the sternal D-ring, which is located at the chest level and is generally used for fall arrest, or the dorsal D-ring, which is typically positioned at the back of the harness and is the primary attachment point for fall arrest systems. The shoulder D-ring, often found on certain harness configurations, can serve various purposes but is not specifically designated for connecting devices to secure positioning in the same way that the positioning side D-ring is. Thus, the distinction of the positioning side D-ring being solely intended for connecting devices reinforces its significance in safety and functionality in height-related work scenarios.
