The ART RopeGuide TwinLine is a new innovation on the RopeGuide friction saver. It is now possible to install the RopeGuide from the ground easily, and through one work step install two lines to the anchor point. This twin-line setup gives the ability to ascend with either SRT or DDRT, or use the long anchoring rope as a second ascent rope for a second climber or rescuer. The integrated ZipAbsorber lowers the impact force in the event of a fall, and the whole system can be quickly and easily retrieved from the ground.
