4. Notice: Do not use mouth
as an adjustable block.
Carbo surface will wear or
wear the line if used as a 2:1
adjustable block under load.
2. Always lash to mouth of the block. Head is not strong enough to secure line.
Planning Installation
1. Lash only to objects with rounded edges. Avoid sharp corners.
WARNING! Lashing to objects with
sharp edges can cause line to chafe
and break suddenly when load is
applied.
2
Mouth
Do not lash through block head.
Head
Do not lash through block head.
Head
WARNING! Lashing to head of block seriously weakens the block. This will cause the
block to break suddenly when load is applied. Always lash to mouth.
3. Use three laps of line to create six strands to match the maximum working load of the block.
WARNING! Using fewer laps will weaken block causing it to break suddenly when
load is applied. Use three laps of line.
Rounded Sharp
This block only has two laps,
four strands of supplied line.
2
Laps
Three laps, six strands are
required for proper strength.

Lashing to Boom
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 another secure knot, get help from professional rigger.

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.

When lashing to a large object such as a boom, cross each line to prevent pushing out on sides of head.
See next page.
Lines can pull
head apart.
Becket Options
Lashing 90°

Lashing to Boom (Continued)
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” on page 3.

Inspect lashing line for chafe or UV-damage every time you sail.
Replace damaged line immediately. Replace line with no
visible damage every two-years. Use Harken replacement
line, but if using own line, see “Using Alternate Line, Knots and
Splices” and chart on page 4 for important information to help
you select the correct line.
Inspect Line Every Time You Sail
4
Check knots or splices before sailing. Use a double fisherman's knot or other secure knot.
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.

Using Alternate Line, Knots and Splices
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®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.
