When choosing a Harken Loup

working load in basket configuration exceeds the maximum working load
of the block.
When choosing a lashing line, use a breaking load that is double the block's
breaking load to account for strength loss from:
1. Knots slipping or breaking at a much lower load than line breaking load.

or Dyneema
®
2. Splices slipping or failing due to incorrect type or execution.
3. UV damage increasing with each passing year.
4. Chafing seriously reducing strength.

Go to www.harken.com/knots for additional information. If you are not
comfortable choosing line, work with a qualified rigger.
Note: See chart for maximum line diameter that will fit through mouth.
WARNING! Knots weaken line considerably. Consult qualified rigger
or line manufacturer for advice on securing line. Use high-strength
loops or consult rigger for recommendations on lashing. Using the
wrong line, or securing the line improperly, can cause an accident.
