Double Fisherman’s Knot Used to connect two ropes of the same diameter –Used to make a prusik loop Lay both ends of the rope next to one another Join the two ropes with a double overhand on each strand Remaining tails must be 2-3” in length
3
Water Knots are used to connect webbing, for Basket hitch anchor material, etc… Tie an overhand knot in one end of the webbing w/a minimum tail of 3” Follow thru the overhand knot w/the second end of webbing and tighten Knot MUST be tight and MUST have a minimum of a 3” tail

Prusik Hitch Multiple uses as a rope grab…. setting up a z pulley system, belay a main line, back-up a rappel, etc... Prusik cord MUST be </= 75% of the diameter of the main line –12 mm rope requires a prusik no larger than 9 mm –11 mm rope requires a prusik no larger than 8 mm –10 mm rope requires a prusik no larger than 7 mm Prusik are multi directional Prusik will slip between 1500 & 2000 lbs Start by placing the prusik loop on the main line w/a girth hitch Wrap the prusik cord around the main line, in between the girth hitch two times –Creating a 3 wrap prusik

Extending an anchor point with a rope Available anchor points are a distance from your work area 1) Tie a loop around your anchor point with a figure 8 follow thru 2) Extend rope to desired work area 3) Tie a figure 8 on a bite to form an anchor point Tree Rope bag 1) Figure 8 Follow thru around anchor point 3) Figure 8 on a bite to form anchor point 2) Extend rope to work area
