Types of D Rings for Fall Protection
When you select fall protection d-rings, you need to understand the main types and their specific uses. Each type plays a unique role in keeping you safe while working at height. The right choice can make a significant difference in both comfort and safety.
Dorsal D-Rings
Dorsal d-rings sit on the upper back of your harness. You use this attachment point for fall arrest systems. When a fall occurs, the dorsal d-ring holds you and connects to lanyards, lifelines, or retractable devices.
The dorsal D-ring is the main attachment point for lanyards, vertical lifelines, and retractables. So when a fall occurs, the D-ring on your back will be the one holding you.
You will find dorsal D-rings marked with an “A” on most harnesses. These d-rings or loops must meet strict safety standards. Manufacturers use strong materials like polyester, nylon, zinc-plated steel, and stainless steel hardware. The table below shows the typical specifications for dorsal d-rings:
Specification | Details |
|---|---|
Materials | Polyester, nylon, EVA, NBR foam, zinc-plated steel, EP-coated steel, stainless steel hardware |
Dorsal D-ring Attachment | 1 dorsal D-ring |
ANSI Weight Capacity | 130-310 lbs. (59-141 kg) |
OSHA Weight Capacity | Up to 420 lbs. (191 kg) |
ANSI Standards | Z359.11-2021 |
OSHA Standards | 1926.502, 1910.140 |
You should always use the dorsal d-ring for fall arrest. Never attach more than one snap hook to this d-ring. This prevents interference during a fall and keeps you safer.
Sternal D-Rings
Sternal d-rings are located at the center of your chest. You use these for specific fall protection tasks, especially when climbing ladders or working in areas with limited free-fall distance. Sternal d-rings provide a secure and stable attachment point, which is essential for vertical climbing systems.
The sternal d-ring is positioned at the center of the chest, providing a secure attachment point.
It is specifically designed for ladder climbing systems and fall arrest systems with limited free-fall, enhancing safety in these applications.
Compared to other d-ring placements, the sternal d-ring is regarded as more secure and stable, particularly in climbing scenarios.
Harnesses with sternal D-rings often use a cross-over style, which increases stability. You will see these d-rings marked as “A” or “A/2.” For fall arrest, you must use both sternal d-rings together if the harness has two.
Side D-Rings
Side d-rings are found at the hips. You use these for work positioning, not for fall arrest. When you need to work hands-free on a pole or structure, you connect your positioning lanyard to the side D-rings. This setup allows you to lean back and use both hands safely.
D-ring Type | Application Description |
|---|---|
Dorsal D-ring marked “A.” | Used for fall arrest; located on the upper back. |
Sternal D-ring(s) marked “A” or “A/2” | Used for fall arrest; front-facing, single or both must be used together. |
Side D-rings (unmarked) | Used for work positioning or controlled movement; not for fall arrest. |
You should never use side d-rings for fall arrest. They do not provide the same level of protection as dorsal or sternal d-rings.
Safety Tips
To keep your fall protection d-rings in top condition, you need to inspect them regularly. Look for any signs of damage or wear before each use.
Inspection Tips for D-Rings in Fall Protection Harnesses |
|---|
Check for distortion, cracks, breaks, corrosion, and rough or sharp edges. |
Ensure D-rings pivot freely. |
Inspect D-ring back pads for damage. |
Always follow the manufacturer’s instructions for use and inspection.
Never connect more than one snap hook to the dorsal d-ring.
Replace your harness if you find any damage to the d-rings or loops.
Tip: Personal fall arrest systems must comply with safety standards such as OSHA regulations and ANSI Z359. These standards ensure that every component, including d-rings, meets strict requirements for strength and reliability.

Bolt-on | Easy installation and removal, suitable for temporary setups | Can compromise safety if improperly installed |
Bolt-On D-Rings
Bolt-on d-rings give you flexibility for temporary or adjustable setups. You attach these rings using bolts, which makes installation quick and easy. You can remove or replace them as needed.
Bolt-on d-rings are widely available and suit many rigging and cargo control applications. However, they may not offer the same rigidity as welded rings, and bolts can loosen over time if not checked regularly.
Type | Pros | Cons |
|---|---|---|
Bolt-On D-Rings | Removable, easy to replace, and widely available | Less rigid than welded; bolts can loosen over time |
Welded D-Rings | Maximum strength and stability | Requires professional installation; permanent |
Note: Always inspect bolt-on d-rings before use. Tighten bolts and check for signs of wear or damage to maintain safety.
Forged D-Rings
Forged d-rings are essential in industrial lifting. Manufacturers use a forging process to create these rings, which increases their strength and durability. You will find forged d-rings in many sectors, including marine, construction, transport, and renewable energy.
These rings serve as anchor points for lifting slings, hoists, and chains. They also help secure heavy equipment and provide safety anchors for rigging operations.
