How Does a Via Ferrata Lanyard Work? (And Why DIY Tethers Are Banned)

Short answer: A via ferrata lanyard is a Y-shaped tether with two arms, each ending in a large locking carabiner, joined to your harness through an energy absorber. You keep the arms clipped to the fixed steel cable. If you fall, the absorber's stitched webbing tears open in a controlled way and slows you down, so the force on your body stays survivable. That energy absorber is why the Ashley Gorge Via Ferrata requires a certified via ferrata lanyard and bans homemade setups.

The Parts

• Two elastic arms: they let you stay clipped while you pass each anchor.
• Two via ferrata carabiners: large, auto-locking and easy to open with one hand.
• Energy absorber: a pouch of folded, stitched webbing that tears progressively in a fall.
• Harness connection: girth-hitched to your harness belay loop or tie-in points, following the manufacturer's instructions.

Why the Energy Absorber Matters

On a via ferrata you are clipped to a cable that is anchored every few meters. Fall above an anchor and you can drop twice the length of your lanyard before anything catches you. A static sling or daisy chain has almost no stretch, so a fall like that can put enough force into your body and the anchors to cause serious injury, or break the gear. The absorber spreads that force out over a longer stop. It's the same idea as a crumple zone in a car.

How to Clip Correctly

1. Clip both carabiners to the cable before you leave the ground.
2. At each anchor, unclip one carabiner, move it past the anchor and clip it back on.
3. Then move the second one. You are never unclipped.
4. Keep a full cable section between you and the next climber.

When a Lanyard Is Retired

After any significant fall, or if the absorber shows signs of tearing, the lanyard is done. Manufacturers also set a maximum lifespan. Every lanyard we rent is a Petzl Scorpio or Salewa Premium Attac, and we inspect each one before it goes out.

Already Own a Harness and Helmet?

The lanyard is the piece most people don't own. Rent just the lanyard for $25 (2 days), or book a full kit for $40. Pickup is 24/7 from our Roosevelt locker on US-40, on the way to Ashley Gorge.
