Master the Descent: A Step-by-Step Guide on How to Rig a Figure 8 Descender Safely
The Figure 8 descender is an iconic and essential tool for anyone working at height. Its simple, reliable design has made it a cornerstone in rock climbing, fire rescue, and industrial rope access for decades. However, its simplicity can be deceptive. Proper rigging is critical to safety.
In this guide, we'll walk you through the correct way to rig a Figure 8 descender, highlight common errors to avoid, and explain why the quality of your hardware-like the DZ Safety Components Figure 8 Descender-is non-negotiable for life-saving equipment.
Why Use a Figure 8 Descender?
Before we dive into the "how," let's review the "why." The Figure 8 offers several advantages:
Friction Control: Provides excellent, predictable friction for a controlled descent.
Versatility: Can be used for rappelling, belaying, and even as a rescue pulley in certain configurations.
Simplicity: Easy to inspect and use, even with gloves or in low-visibility conditions.
Durability: A well-made Figure 8, like those from DZ Safety Components, is built to withstand extreme forces and abrasive environments.
Step-by-Step: How to Rig Your Figure 8 Descender
⚠️ Safety First: Always perform a pre-use safety check on your harness, rope, and all hardware, including the descender. Ensure you are trained by a competent professional before attempting any descent.
Step 1: Identify the Parts
A Figure 8 has a large ring ("eye") and a small ring ("ear"). The ear creates a V-notch that generates friction.
Step 2: Create the "Rack"
Hold the descender with the small ear pointing away from you.
Take a bight (loop) of the rope and pass it through the large ring from the back to the front.
Step 3: Lock It In
Bring the loop of rope over the top of the large ring.
Pull it down and loop it behind the small ear.
The rope should now be securely "racked" in a "Q" or "P" shape configuration. A quick visual check: the rope running to your anchor (the brake side) should be on the same side as the small ear.
Step 4: Connect to Your Harness
Clip the large ring of the rigged descender into the load-bearing carabiner on your harness's belay loop.
Ensure the carabiner is auto-locking and rated for life support (e.g., meeting EN 362 standards). For a reliable connection, explore DZ's range of certified safety carabiners.
Step 5: Brake Hand Position
Your dominant hand is your brake hand. It should always grip the free end of the rope (the end going to the ground) behind your hip.
Your other hand guides on the rope above the descender.
Never let go of your brake hand.
Common Mistakes to Avoid
Incorrect Racking: Rigging the rope over the large ear instead of the small one drastically reduces friction and can lead to a runaway descent.
Wrong Carabiner: Using a non-locking or lightweight carabiner is a severe failure risk.
Poor Brake Hand Discipline: This is the most common cause of accidents. Practice until it becomes muscle memory.
Using a Worn-Out Descender: Regularly inspect your gear for sharp edges, cracks, or excessive wear that can compromise strength.
