(1) Position the snap hook so the opening is facing outward; lay the static line flat; ensure the
green ID marking thread is on top, also ensure the green ID marking thread is on the outside
of the 3½-inch loop.
(2) Pass the 3½-inch loop end of the static line through the opening in the base of the snap hook,
from the bottom to the top. Pass the top of the snap hook through the static line loop.
(3) Continue passing the snap hook through the static line loop; pull the excess static line back
through the opening in the base of the snap hook until the loop is past the snap hook opening.
Turn the 3½-inch loop outward so the green ID marking thread is now on the inside.
(4) Slide the loop down to the bottom of the snap hook until the static line is fully seated in the
indents on the side of the snap hook, forming a taut girth-hitch. Ensure there are no twists in
the static line snap hook loop.
e. Attach the 5-foot extension to the USL 15-foot configuration:
(1) Pass the 3½-inch loop on the 15-foot static line through the 2-inch buffer loop on the static
line extension for the 20-foot static line.
(2) Pass the snap hook of the extension for the 20-foot static line through the 3½-inch loop on the
15-foot static line.
(3) Continue passing the snap hook through the 3½-inch loop until a taut girth hitch is made
securing the extension for the 20-foot static line to the 15-foot static line. There will be a half-
twist in the 3½-inch loop when forming the girth-hitch.
2. Stowing the USL 20-foot static line. Stow the USL 20-foot static line in accordance with the

(1) Remove the snap hook by grasping the sewn portion of the static line just below the snap
hook.
(2) Push the static line towards the snap hook, this will allow you to loosen the girth-hitch. Once
you have loosened the girth-hitch, push the 3½-inch loop up the sides of the snap hook. Then
push the static line from the bottom to the top so that you can pass the 3½-inch loop over the
top of the snap hook.
(3) Pull the static line back through the opening in the base of the snap hook.
d. Remove the 5-foot static line extension:
(1) Secure the extension for the 20-foot static line in your right hand and grasp the 15-foot static
line with your left hand.
(2) With the left hand push the 15-foot static line towards the extension for the 20-foot static line.
Once the girth-hitch is loosened, pull the webbing of the extension for the 20-foot static line
through the 3½-inch loop on the 15-foot static line, until it is removed from the 15-foot static
line.
