You Must Supply
1. Loop and/or high strength lashing line
Harken is not liable or responsible for choosing line used to secure
blocks. Go to Harken Limited Warranty at www.harken.com/manuals
for complete details.
Refer to the “Specifications Chart” below and use a loop/lashing with
a maximum working load that meets or exceeds the maximum working
load listed. If working with breaking loads, use a breaking load that is
four times the maximum working load listed.
Important information on choosing line, knots and splices:
See www.Harken.com/knots.
2. Secondary lashing line
Use for securing loop or lashing to head. Use small diameter line.
Line length will vary depending on block.
WARNING! Knots weaken line considerably. Work with a qualified
rigger or line manufacturer on securing line. Use high strength
loops carefully chosen using the instructions in “1” above or
consult rigger for recommendations on lashing.
