WARNING! Webbing or smaller lashings can be damaged by being
pinched between post and sideplate. Damaged webbing or lashings
can part suddenly under load. Use only loops when terminating at
dead-end post.
WARNING! Knots weaken line considerably. Consult qualified rigger
or line manufacturer for advice on securing line. Use high strength
loops or consult rigger for recommendations on lashing. Using the
wrong line or securing the line improperly can cause an accident.

personal injury or death. See www.harken.com/manuals for additional safety information. = Incorrect. Avoid to prevent accidents.

Terminating to Dead-End Post 5. Open sideplates without
pulling line through block.
Terminating to dead-end post lets you attach block to a closed bail such
as a padeye.
1. Remove screw..
3. Insert loop into block
mouth as shown.
4. Pass loop ends through
mouth so loops extend
beyond block's sideplates
as shown.
2. Remove dead-end post.
6 Part legs of loop and insert
dead-end post. Make sure
dead-end post is seated
straight in sideplate. Put
sideplates together.
7. Pull loops to seat ends
on dead-end post.
8. Reassemble block using
blue Loctite®on screw.
Sideplates are not parallel

WARNING! Webbing or smaller lashings can be damaged by
being pinched between post and sideplate. Damaged webbing
or lashings can part suddenly under load. Use only loops when
terminating at dead-end post.
WARNING! If sideplates are angled to one another, dead-end post
is not seated correctly. This will cconsiderably weaken the block so
it can easily break under load. Block sideplates must be parallel to
one another when assembled.

9. Lash loop to head of
block with small control
line using a Carrick bend or
a square knot and run tail
up behind wrap, then down,
and under itself on each side
of knot. Pull tight to secure.
For knot tying resources see
www.harken.com/knots.
Terminating Loop Outside Block or Using Lashing
1. Use allen wrench
to remove screw.
If terminating line outside block or lashing using multiple strands
of smaller-diameter line you must remove the dead-end post.
2. Remove dead-end post.
If lashing comes loose block
can flip so that sheet rides
off sheave.
Dead-end post
10. Further secure stop knot
by carefully melting line
ends with a hot knife.
3. Re-assemble block. Use
blue Loctite®on screw.
5. Secure stop knot by
carefully melting line
ends with a hot knife.
4. Lash loop to head of
block with small control
line using square knot. Run
line ends up and behind
lashing, then down and
under itself on each side
of knot. Pull tight to secure.
WARNING! If lashing comes loose, block can flip and cause line
to jam, resulting in loss of control. Inspect lashing often and
redo if necessary.
WARNING! Attaching line to block head will considerably weaken
block so it can easily break under load. Attach loop/lashing only
through mouth of sheave.
Do not attach
to head

Harken equipment is designed for minimal maintenance, but some maintenance
is required to give the best service and to comply with the Harken limited warranty.
Cleaning: Flush blocks and loops/high strength lashing lines thoroughly with fresh
water. Periodically, disassemble the blocks and clean with detergent and fresh water.
When assembling block, make sure screws and holes are dry. Use blue Loctite®to
secure screw before assembling.
Important: Exposure to some teak cleaners and other caustic solutions can result
in discoloration of part and is not covered under the Harken warranty.

Inspect Parts Every Time you Sail
1. Inspect block to make
sure that screw is secure.
If screw is loose, remove
it, use blue Loctite®to hold
it in place and retighten.
2. Inspect sideplates to
make sure they are parallel
to each other. If they are
angled dead-end post may
not be seated. Take block
apart, install bail correctly
and secure with screw and
blue Loctite®.
3. Inspect loops and lashings. Replace if there are signs of wear or if the
colored tracer fades from UV damage.Pull loop out of mouth and inspect
loop/lashing carefully for any signs of wear, UV-damage, fatigue or strand
separation. Replace loop if it shows signs of UV-damage or wear.
4. Inspect lashing at head
of block to make sure knot
is holding tightly.
For additional safety, maintenance and warranty information see www.harken.com/
manuals or the Harken®catalog.
ALL INSTALLATIONS
Anchor Point Chafing or Cutting
Loops must be attached to round bails such as those found on padeyes
or pins. Sharp edges on many perforated toerails will cut loop, severely
weakening it. When loop is attached to a plate, it must be at least 1/4"
thick and have rounded edges to keep loop from being damaged.
Sharp edges will
damage loop
Round edges to prevent
damage to loop
WARNING! Failure to inspect and correct block and loop or
lashing may result in block breaking under load. Inspect parts
each time you sail. If parts are under load during long passages
it is important to inspect them carefully while in use.
WARNING! Loops or lashings running over a sharp edge can cause
part to break under load. Attach to fitting with a rounded edge.
WARNING! Failure to replace damaged or weakened parts can
cause part to break under load. Replace all loops and lashings
every year or if there is any sign of wear, UV damage, fatigue
or strand separation. If in doubt replace. Consult chart to match
strength of loop/lashing to block and load.
Maintenance
WARNING! Using a loop in a choker style weakens the loop
connection. Do not use choker style connection.
