The climbing world is rife with stories of mishaps and tragedy, and that is because mishaps happen. Recently, we at NCMG have been thinking a lot about climbing safety. There are many factors in climbing that could lead to a mishap, but a disproportionately large sum of incidents occur while rappelling. There are a couple factors that can help to avoid a rappelling mishap.

You can do two things:

1) always tie knots in the ends of your rope, and

2) implement a safe personal anchor system that works for you.


Personal anchor systems

There are a lot of options out there. One important factor is that your system needs to be as easy as possible to use so that you will actually use it every time. This personalized system must be

1) safe

2) practical and

3) efficient.

I believe a Personal Anchor System (PAS) should be versatile as well. For instance, I like to use a double-length sling girth-hitched through my harness with a knot in the middle. With this system, I can easily connect to an anchor at the top of a pitch, and when rappelling, I am able to extend my rappel device off my harness with a third hand auto block off my belay loop.  I like it. It works great. To learn more about how this system works, you can look here. Another option is Sterling’s Chain Reactor. It was designed more specifically for this application. But unlike the Chain Reactor, double-length slings are easy to use later as anchor-building material, which makes them a more versatile option.

A great new product on the market is the Petzl Dual Connect. It has a few advantages to a both a double length sling or Chain Reactor. Below I will address the pros and cons of this cool new product.





The coolest feature is the metal handle doohickey you move to adjust the length. It is easily operated with one hand. To tighten, you grab the free end of the rope and pull in slack. To loosen, you rotate the metal handle doohickey to release rope tension.

With the carabiner loop, you can securely attach an extended rappel carabiner. The loop is enclosed with a plastic housing that grabs the carabiner and keeps it snugly oriented in place.


The Dual Connect is made of cord instead of webbing. Cord, like your climbing rope, is more dynamic and better for factor falls. With the metal adjustor, you are are able to precisely adjust your tether length.

Not cheap

If you have $60 to throw around, this is a snazzy option.


Heavier than the alternatives

Black Diamond 120cm 18mm sewn nylon runner: 2.4oz

Sterling Chain Reactor: 4.8oz

Petzl Dual Connect: 5.6oz


It might get in the way of other gear

Because of its design, you will be less likely to untie the Dual Connect from your harness. This means It might get in the way of other gear around your belay loop and gear loops. To make this product work for you, you will have to find a reliable place to store it.


The "adjustor" is a bit finicky

The adjustor, doohickey, what-have-you, is a bit tough to handle in tight spaces and more suited to metal hangers than crowded master points. It is not great for hanging belays where releasing tension is more challenging.

The Dual Connect is an expensive PAS alternative that allows for easily adjustable anchoring and extended rappels. You can use it in many applications, from multi-pitch climbing to sport climbing. A double-length sling works fine as well. Like other Petzl products, the Dual Connect looks cool. It is an interesting product which represents a new generation of specialized, versatile PAS systems. There is nothing quite like the new line of Petzl lanyards.
