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.
WARNING! Using fewer laps will weaken block causing it to break suddenly when
load is applied. Use three laps of line.
4. IMPORTANT! 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. Ratchet mechanism will only work with lashing line on trigger.
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.

Do not lash through block head.

WARNING! Lashing to objects with sharp edges can cause line to chafe and break suddenly
when load is applied.
3. Use three laps of line to create six strands to match the maximum working load of the block.
Rounded Sharp
This block only has two laps,
four strands of supplied line.
2
Laps
Three laps, six strands are
required for proper strength.
Head

Ratchet blocks are hand and crew savers. The eight-sided sheave grips loaded sheets with up to 10:1
holding power. Ratchamatic blocks spin freely in both directions under low load. At higher load, ratchet
engages, providing holding power. As the load decreases, the ratchet shifts back into light air mode
and free spins. Unloaded main and jib sheets run out freely during mark roundings and asymmetrical
spinnakers run free during jibes.
Ratchet Direction Arrow on side of block shows direction that sheave will spin in ratchet mode.
Refer to arrow when reeving block.
Inspect Line Every Time You Sail
3
Using T2 Ratchamatic Block
Check knots or splices before
sailing. Use a double fisherman's
knot or other secure knot.
See www.harken.com/knots
WARNING! Failure to inspect and correct knots can cause the line to slip suddenly when
load is applied.

WARNING! Failure to inspect and replace UV-damaged, worn or frayed line can cause
the line to break suddenly when load is applied.
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 back page for important information to
help you select the correct line.

Lashing to Boom
Lashing to Bail Using Harken-Supplied Line
Note sheave direction of rotation when block is under load in ratchet mode. Make sure the block is
facing the correct way before lashing. Use three laps to create six strands. Tie ends using double fisher-
man's knot or other secure knot. Knot can also be located on side of block. 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 a professional rigger.
4
To lash block at 90° cross lines
each pass similar to 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.
Lines can pull block head apart.
Lashing 90°
If you have access to end of
boom, twist each lap. Secure
using double fishermans knot or
other secure knot. See "Lashing
to Bail Using Harken-Supplied
Line" below.

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 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 exceeds 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/knots for additional information.
IMPORTANT! Fewer lashing strands require line with higher breaking load.
Notes
A breaking load of 2000 lb (900 kg)
can be achieved by using:
Fewer strands of higher-strength line
OR
More strands of lower-strength line
Check fit of lashing line in block mouth
