2.3.3 STEERING LINE ATACHMENT METHODS
2.3.3.1 OVERVIEW
The parachute manufacturer allows the rigger to use either of the two following methods for attaching the
reserve steering toggle to the lower steering line.
A. Secure the steering toggle to the lower steering line by the use of a secured routing and finish knot.
B. Secure the steering toggle utilizing a Larkshead knot and loop.
This is the method we will discuss in this publication.
LARKSHEAD METHOD
Secure the steering toggle to the lower steering line by making a larks head knot with a pre-made loop at the
end of the steering line terminal end.
CPS-TM-PUB-36-R2- 3
2.3.4 STEERING LINE LENGTH SPECIFICATIONS FOR LARKSHEAD ATTACHMENTS
2.3.4.1 All measurements are in inches and are based on the original factory toggle mark distance from the
top of the cat-eye toward the terminal end.
NOTE: Factory mark length equals the finished length.
2.3.4.2 Use a different color ink to place reference the marks in order to distinguish between the factory mark
and the reference marks.

2.3.5 STANDARD TOGGLE LARKSHEAD ATTACHMENT PREPARATION-SMALLER LOOP
2.3.5.1 The factory mark distance from the
top of the cat-eye for each model and size
can be found in Table 2-1.
(See figure 2-1)
Figure 2-1. Factory Toggle Mark
2.3.5.2 Working towards the cut tail, place a
mark at each of the following locations:
• 1/2 inch from the original mark towards the
tail.
• 3-1/2 inches from the original mark towards the tail.
• 6-1/2 inches from the original mark towards the tail.
This is the cut mark.
Use a different color ink than the factory
placed mark to help distinguish between the
original and the newly place marks.

at a 35-45 degree angle using scissors.
(See figure 2-3)
Do not use a hot knife.

2.3.5.4 Insert the finger-trapping tool into
the line at a distance greater than the
amount of line being finger-trapped. The
finger trap tool should emerge at the 1/2
inch mark drawn in step 2.
The line between the 3-1/2 inch mark and
the 6-1/2 inch mark is the portion to be finger trapped.
(See figure 2-4)
Figure 2-4. Finger Trap Tool Insertion
2.3.5.5 Insert the terminal end of the line
through the eyelet of the finger-trapping
tool.
(See figure 2-5)
Figure 2-5. Insert The Tail Of The Line
2.3.5.6 Pull The line through until the 3-1/2
inch mark and the 1/2 inch mark are in
alignment.
Remove the finger trap tool.
(See figure 2-6)
NOTE: Ensure that the terminal end remains completely inside the line.

2.3.5.7 Place a 3/4 inch bartack at 42
stitches per inch at the fingertrap insertion
point (1-1/4 inch from the beginning of loop)
to secure the fingertrap.

2.3.6 Installing The Toggle Using The Larkshead Method.
2.3.6.1 Route the steering line down
through the guide ring located on the riser.
NOTE: Prior to hooking up the steering
toggles, make sure the steering line passes
through the grommet on the slider.
(See figure 2-10)
Pass the steering line through the
steel guide ring only!
DO NOT pass through the locking
loop

2.3.6.2 Thread a piece of waxed nylon tack
cord through the steering line loop. Put both
ends of the tack cord through the toggle
grommet from the Velcro™ side.

2.3.6.3 Thread the toggle handle through
the finished loop creating a larks head knot.
Do not thread the upper end of the toggle
through the loop, this is not a secure method and may detach.
(See figure 2-12)
Figure 2-12. Thread Toggle Handle Through Line Loop
2.3.6.4 Pull the toggle completely through
and tighten the loop around the toggle.
Repeat this procedure for the other steering
line.

2.3.7 HAHO (High Altitude High Opening) TOGGLE LARKSHEAD ATTACHMENT PREPARATION.
The following procedure will result in a larger loop required to install the larger HAHO
toggle with very little difficulty. Make special note of the changes in the measurements.
2.3.7.1 The factory mark distance from the
top of the cat-eye for each model and size
can be found in Table 2-1 at the beginning
of this publication. Working towards the cut
tail, place a mark at each of the following
locations:
• 1/2 inch from the original mark towards the
tail.
• 4-1/2 inches from the original mark
towards the tail.
• 7-1/2 inches from the original mark
towards the tail. This is the cut mark.
Use a different color ink than the factory
placed mark to help distinguish between the
original and the newly place marks.

2.3.7.3 Insert the finger-trapping tool into
the line at a distance greater than the
amount of line being finger-trapped. The
finger trap tool should emerge at the 1/2
inch mark.
The line between the 4-1/2 inch mark and
the 7-1/2 inch mark is the portion to be
finger trapped.

2.3.7.4 Insert the terminal end of the line
through the eyelet of the finger-trapping
tool.
(See figure 2-22)
Figure 2-22. Insert The Tail Of The Line
2.3.7.5 Pull The line through until the 4-1/2
inch mark and the 1/2 inch mark are in
alignment.
Remove the finger trap tool and ensure
that the terminal end remains in completely
inside the line.
(See figure 2-17)
NOTE: Ensure that the terminal end remains completely inside the line.

2.3.7.7 Double check your measurements
against the ruler. The distance from the
top of the cat-eye to the new marks made
should be equal to the distance measured
to the factory mark before the line was finger trapped and bartacked. For the MS-360
that would be 23”. (example)

2.3.8.2 Remove the HAHO extension in
order to easily compress the toggle to pass
it through the larkshead loop.
(See figure 2-22)

2.3.8.4 Being careful to protect the line
from any hook Velcro™ on the toggle,
thread the toggle handle through the finished loop creating a larks head knot.
Do not thread the upper end of the toggle
through the loop, this is not a secure method and may detach.
(See figure 2-24)
