Lashing
Lashing

A means of fastening two poles (or spars) together
Qualities of a Good Lashing


Firmness – it should be string and tight, or else it is likely to fall
apart when put under strain
Neatness – proper steps should be observe because incorrect
lashing can easily loosen
Knots and Hitches used in Lashing

Stopper Knots – used to lock and prevent slipping of a clove hitch



Example: Overhand, Figure of Eight, etc.
Clove Hitch – used to start and finished almost all lashing
Timber Hitch – Used to start a diagonal lashing because of it’s
ability to tighten.
Parts of Lashing


Wrapping – for connection
Frapping – for tightening
Kinds of Lashings
Diagonal Lashing
 Square Lashing
 Shear Lashing
 Round Lashing
 Figure Of Eight Lashing
 Continuous Lashing
 Malay Hitch

A. Diagonal Lashing


Used where two spars are likely to be
pulled apart
Procedure
1.
2.
3.
4.
5.
Start with the timber hitch along the two spars
Wrap at least 3 times along each of the
diagonal s of the spars
Frap at least 3 times between two spars
End with a Clove Hitch in any of the spars
Lock with a stoppers knot

B. Square Lashing


Used where 2 spars cross one another
and have to be joined, or where the load
on one spars might tend to make a slip
over the other
Procedure
1.
2.
3.
4.
5.
Start with clove hitch along one spar
Wrap at least 3 times around both spars alternately
(over and under)
Frap at least 3 times between 2 spars
End with a clove hitch along the other spar
Lock with a stopper knot
Square Lashing Picture
C. Shear Lashing


Used for spars which will either lift or support
weights. Where it’s used to join two spars to
increase overall length
Procedure
1.
2.
3.
Start with a clove hitch along one spar
Wrap at least 4 times around both spars
Frap at least 3 times between 2 spars

5.
The frapping turns will be difficult to do. In this case, drive
in wedges between 2 spars to leave space.
End with a clove hitch on the other spar
Lock with a stopper knot

D. Round Lashing


It is used to join or connect two spars to
increase overall length
Procedure
Almost the same as in shear lashing.
2. Frapping is not applied, and both spars will
be tied with a clove hitch

Round Lashing Picture
E. Figure of Eight Lashing

Used for joining three or more spars
together


Most useful for doing tripods
Procedure
1.
2.
3.
4.
5.
Start with a clove hitch along one poles
Wrap at least 3 times around the spars
alternatingly (over and under)
Frap at least 3 times between the spars
End with a clove hitch along the other end of the
spar
Lock with a stopper knot
Figure of Eight Lashing Picture
F. Continuous Lashing

Used in joining a number of spars or strips along
a single spar or support


Most useful in making mating for tables, etc.
Procedure
1.
2.
3.
4.
5.
6.
Make a bight along the center of the rope
Knowing the center of the rope, make a Clove Hitch
along the center and tie it on the spar support
Lie perpendicularly along the support the spars to be
tied
With the 2 end rope, go over the spar and cross under
the support. Continue until all spars are tied to the
support
End each end rope with a Clove Hitch
Lock with a stopper knot
Continuous Lashing Picture
G. Malay Hitch

Used in joining several pieces of spars along each other
without a support


Most useful in making matings for camp tables, towers, etc. before
a camp and then rolled up for portability
Procedure
1.
2.
3.
4.
5.
6.
Make a bight along the center of the rope
Knowing the center, make a Clove Hitch and tie it around the 1st
spar
With the 1st end rope, go over and around the 2nd spar and to the
3rd and so on in a circular motion
Do the same process with the 2nd end rope, but instead of going
over, go under the second spar making it alternate to each other
Finish both end ropes with a Clove Hitch along the last spar
Lock with a stopper knot
