WARNING! Improper knots or splices can weaken the block installation causing it to break

suddenly when load is applied.

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.

Harken is not liable or responsible for use of line used to secure blocks. Go to Harken Limited Warranty at www.harken.com

for complete details. It is your responsibility to choose the correct line for the block. When choosing line, use a breaking

load that exceeds the block's breaking load to account for strength loss from:

1. Knots slipping or breaking much lower than line breaking load. Spectra

®

or Dyneema

®

-type 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/knots for additional information.

IMPORTANT! Fewer lashing strands require line with higher breaking load.

Notes

A breaking load of 2000 lb (900 kg)

can be achieved by using:

Fewer strands of higher-strength line

OR

More strands of lower-strength line

Check fit of lashing line in block mouth
