Single Rope Techniques (SRT) have long been used in caving, mountaineering and tree canopy access. Climbers set a line in place and use various techniques to climb and descend the line itself. SRT has become a big part of many tree climbers' strategies for ascent. Recent gear innovations have provided methods to not only ascend but to perform tree work on SRT.
SRT is fundamentally different to DdRT. The climber moves along a single line that doesn't need to move. There is no mechanical advantage of the doubled rope, and the rate of ascent and rate of travel on the rope are at a 1:1 ratio. SRT climbing is frequently used for long ascents, or to more easily install a line as there is no need to isolate the primary suspension point.
Complete SRT climbing kits and SRT upgrade packages are a cost-effective way to get geared up for Single Rope Technique climbing.
The RopeTek Hitch Hiker is a great device for Hybrid climbing systems, and improves climbing in both single rope and doubled rope climbing systems.
Adjustable anchor slings for your SRT system have the advantage of fitting a large range of trees, being easy to install, and making it easy to attach belay devices to lower off the climber if needed.
The Rope Wrench takes some of the pressure off of your friction hitch allowing you to climb single rope on your prussik cord. A great invention for SRT climbing. Works best with a Stiffy Tether.
Kernmantle ropes make the best climbing lines for SRT ascents. Here you'll find the best lines for SRT from Samson, Yale, Sterling, and other top arborist rope manufacturers.
