About the Course

We typically start the Arbor: Work At Height course with an overview of the Moving Rope System (MRS)  — also known as the DdRT or Doubled Rope system — that’s in use by a majority of arborists worldwide. Why? To better understand both the positive and negative aspects of MRS climbing and to point out that many of the climbing systems that we view as “safe” are only safe if we apply them correctly.

We want to stress that the intent of this course is not to show that a Stationary Rope System (SRS) — also known as the SRT or Single Rope Technique — is superior to MRS in every possible way, but to highlight that the SRS is simply another set of options. Really, it's a new range of options that, if used properly, can complement the MRS options that you already have in order to make working in trees potentially safer and more efficient.
