Special equipment: 3, 5, 7 and 9-foot lengths of 5-mm or 6-mm kernmantle. Two 8-foot and one 10-foot length of 1″ tubular webbing.
All required knots will be shown by the instructor and tied by the students. All knots must be practiced at home, and students must be proficient in tying them before the First Rock Day. A Knot Test will be given after the third lecture. Continuation in the School will be dependent on the ability to tie these knots quickly and neatly and under possibly adverse conditions.
