8mm ropes are lighter, stronger and pack down smaller than the 11mm rope. 11mm ropes are optimized for use with the Ropeman 1 Ascender. 8mm ropes work with Kong Duck or Ropeman 4 Ascender. 8mm Tree TetherFACTORY SPLICED EYES ARE A BIG DEALWith this rope we were able to develop the world’s first commercially available 8mm rope with a factory spliced eye. This is a big deal because splices are much stronger than knots by anywhere from 30%-50%. Our splices tested at over 90% rope strength. This is simply not possible with knotted loops.Spliced eyes also reduce the weight and bulk of the rope by eliminating big knots.The 8mm Tether includes 8′ rope with one 5″ factory-spliced eye, 1 ultra lite carabiner, and cornell hitch.Strength: 9,000 lbsSize: 8mm x 8′ double braid, DynaLite™ CoreLoop: 5″ Factory-spliced eyeColor: Brown Weight: 8mm 10.28 oz 11mm Tree TetherThe Tree Tether is one of the most important pieces of kit in your arsenal.
