The US Department of Agriculture Climbing Guide, section 6.3, discusses the "Four Inch Tie-In System" for access trees above a 4-inch bole diameter.
Does anyone here use the Four Inch Tie-In System?
If so, does anyone know of a place I can buy a kit with all the parts?
Honestly, most are already in my tool bag such as carabiners and slings. Can someone recommend a dynamic rope to use with it? That does not seem to be commonly available at an online arborist store and is more like something a rock climber would use. The US Department of Agriculture Climbing Guide describes a dynamic rope as one that "... has an elongation of 40 to 60 percent at the breaking strength and less than 10 percent elongation at a working load of 176 pounds. A dynamic rope absorbs the shock of a fall, giving the climber added protection. Principal uses for dynamic ropes include safety lines and 4-inch tie-in systems"
Thanks in advance!
