Chicks Gear Review: Sterling’s Chain Reactor

Personal Anchor Systems (PAS) replaced Daisy Chains years ago as superior solutions for anchoring yourself while cleaning anchors at the top of sport routes, setting up TR’s, rappelling, canyoneering, partner rescue and transitioning from up to down on multi-pitch climbs. Sterling’s Chain Reactor is the superior product on the market for a number reasons.

Sterling Rope Chain Reactor
The Chain Reactor and Chain Reactor Pro are rated to 12.7 and 14KN respectively. Each loop is full strength and can hold more of an impact than your body could actually withstand. Because it’s constructed of entirely of nylon as opposed to Dyneema, it has dynamic properties that enable it to handle up to 3 factor 2 falls which although highly unlikely, increases my confidence when using it as a sole attachment point.

When used as a rappel extension, both models have attachment points that help prevent a carabiner from rotating and cross loading. These attachments are also the perfect distance from the harness, enabling you to use your gear loop as opposed to your leg loop for a third hand friction hitch back-up.

The Pro version attachment to the harness is doubled, which for heavy use is the the best choice. The classic Chain Reactor is lighter, which for multi-pitch routes is my go to. Sterling Rope products are all made in the U.S.A. and individually hand checked to maintain Sterling’s high quality. The company is founded and run by a woman who has put together an incredible team to produce and insure that all of their products meet international ISO and EN standards.

Sterling is also a long time supporter of women’s climbing and Chicks’ Official Rope Sponsor.

Chicks Tech Tip: Personal Anchoring Systems

One thing you’ll notice between recreational and professional climbers at the crag or on multi-pitch routes is the pro’s Personal Anchoring Systems (PAS) is nowhere to be seen on their harness. It’s in their pack, used solely for the descent. Recreational climbers have adopted many techniques guides use, such as direct anchor belays and rope management strategies, but the way we use PAS’s has been slow to gain foothold. Instead, many recreational climbers keep their PAS girth hitched to their tie-in’s or belay loop and tucked between their legs or off to the side.

Why don’t professionals do this? Because, the rope is the strongest part of the entire system. Why would we use anything else to attach ourselves to the anchor when we are already tied into the rope when climbing? Arguments in opposition often suggest that the rope attachment isn’t adjustable. Look at how any professional anchors themselves with the rope and you will almost exclusively see the clove hitch, which is undeniably appropriate and fantastically adjustable.

Countless tests and videos have demonstrated the risk of using a PAS as a direct attachment to the anchor. It’s common knowledge that any small fall directly on an anchor with a PAS or sling generates forces significant enough to result in sling failure. In 2007, a climber on the Grand Capucin in Chamonix, France fell less than two feet onto a Dyneema sling attaching him to the anchor. It failed and he fell to his death.

How might this relate to us? Shifting around on an anchor and taking a small slip while pulling ropes, a foothold breaks, making a move that’s a stretch to thread the rap rings or just not paying attention and falling off a small ledge. Shit happens but accidents can be prevented. By keeping the PAS or sling tether fully loaded you have eliminated the risk.

Other reasons pro’s don’t keep their PAS tethered to their harness include; 1) increased wear overtime decreases its integrity when attached to the same points on the harness all the time, 2) it gets in the way of gear and adds clutter to the harness and 3) bottom line, it’s only a tool for transitions and descents.

PAS vs. Slings? Often I use a 48” nylon sling as a tether for descents on long multi-pitch routes because it’s multi-purpose and lightweight. I keep it on my harness and use it for anchors or sling extensions. Why is this okay here and not for a personal tether? Because, while climbing the rope is always part of the system and adds dynamic properties that absorb energy. When I’m not concerned with weight or I have to do many rappels, my Sterling Chain Reactor is always in my pack. It’s more elegant than a nylon sling tether and its full strength loops provide excellent adjustability to prevent me from allowing slack into the system, reducing the risk addressed above.

No mention of Daisy Chains? They have no place here because they are only intended for aid climbing, not personal anchoring systems.
