WARNING! Lashing to objects with sharp edges can cause line to chafe and break suddenly
when load is applied.
Using Alternate Line, Knots, and Splices
Harken is not liable or responsible for use of line used to secure blocks. Go to Harken General Warnings
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. Go to www.harken.com/manuals for
additional information.
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® equipment is designed for minimal maintenance. However, some upkeep is required to give
the best service and comply with the Harken® limited warranty.
Keep your equipment clean and free-running by frequently fl ushing with fresh water. Periodically
clean with mild detergent and water solution. Spin sheaves to distribute soap solution evenly.
Flush with fresh water.
Important: Exposure to some teak cleaners and other caustic solutions can result in discoloration
of part and is not covered under the Harken warranty.

2. Always lash to mouth of the block. Head is not strong enough to secure line.
WARNING! Lashing to head of block seriously weakens the block. This will cause the block
to break suddenly when load is applied.
Additional Information
For additional information, including use of block mouth as a becket, go to online manual 4370 at

WARNING! Using fewer laps will weaken block causing it to break suddenly when load is
applied.
Lashing to Boom
When lashing to a large object such as a boom, cross each line to prevent pushing out on sides of head.
See next page.
Inspect Line
Check knots or splices before sailing. Use a double fisherman's knot or other secure knot.
If you have access to end of boom, twist each lap. Secure using double fisherman’s knot or other secure
knot. See "Lashing to Bail Using Harken-Supplied Line" below.

3. Use three laps of line to create six strands to match the maximum working load of the block.
Lashing to Bail Using Harken-Supplied Line
Use three laps to create six strands. Tie ends using double fisherman's knot or other secure knot. Knot
can also be located on side of block or inside the mouth. Photos are not intended to teach this knot. See
www.harken.com/knots or consult a knot tying book. Important: If you are not comfortable tying this
or other secure knots get help from professional rigger.
Periodically inspect lashing line for chafe or UV damage. Replace damaged
line immediately. Replace line with no visible damage every two years.
Use Harken replacement line, but if using your own line, see “Using Alternate
Line, Knots, and Splices” and chart on back page for important information
to help you select the correct line.
This block only has two laps,
four strands of supplied line.
WARNING! Failure to inspect and replace UV-damaged, worn, or frayed line can cause
the line to break suddenly when load is applied.
WARNING! Failure to inspect and correct knots can cause the line to slip suddenly when
load is applied.

Laps
Three laps, six strands are
required for proper strength.
To lash block at 90° cross lines each
pass similar to lashing to boom.
Use a spliced or tied loop (not supplied) to
create a becket or splice directly to mouth.
Make loop or eye splice long enough so
“X” is longer than sheave diameter “Y”.
A short loop can cause sideplate to bind
against sheave.
