Where to knot the string.

To install, knot the string to the device through the provided hole. Add knots at 57.3/2 and 57.3/3. Measure a length of 57.3 cm (22.56 inches) from eye to device. Make a small loop at the end to fasten the plumb line weight; for measuring distances, hold onto the string with your teeth or hold the respective knot up to eye level.

Positioning the Knots

How to position a knot at an exact measurement on a string.

How to position a knot at an exact measurement on a string.

  1. Make an overhand knot and guide an awl, needle, or equivalent through the loop.
  2. Optionally, or for very thin string (below 0.35 mm), thread a short piece of string through the loop.
  3. Carefully tighten the knot around the awl and the extra piece of string and slide the knot laterally along the string, using a ruler, to the intended position.
  4. Fully tighten the knot and remove the awl. You now have a knot determining an exact length. Use different color of string for the extra thread for additional marking purposes.
