Planning Installation
Loop only to objects with rounded edges. Avoid sharp corners.
WARNING! Loop can cut easily on sharp corners causing loop to break suddenly under load,
possibly causing an accident.
Using Alternate Line, Knots and Splices
WARNING! Improper knots or splices can weaken the block installation causing it to break suddenly
at high loads, possibly causing an accident.
WARNING! Failure to account for loss of strength due to chafe or UV damage when choosing
line can result in line breaking suddenly at high loads.

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 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
®
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 or use Harken-supplied Loops 2148
or 2151. Go to www.harken.com/knots for additional information.
