Harken is not liable or responsible for use of line used to secure blocks. Go to Harken Limited Warranty at
www.harken.com/manuals for complete details. It is your responsibility to choose the correct line for the
block. When choosing line, use a breaking load that is at least double the block's breaking load
to account for strength loss from:
1. Knots slipping or breaking much lower than line breaking load. Spectra
lines require specialized knots.
2. Splices slipping or failing due to the incorrect type or execution.
3. UV damage increasing with each passing year.
4. Chafing seriously reducing strength.
If you are not comfortable choosing line, work with a qualified rigger. Go to www.harken.com/manuals
for additional information.

WARNING! Failure to account for loss of strength due to chafe or UV damage when choosing
line can result in line breaking suddenly when load is applied.
WARNING! Improper knots or splices can weaken the block installation causing it to break
suddenly when load is applied.
