6.3.1 Description— Double coil Type II is constructed of
one 24 in. diameter helical coil inside a 30 in. diameter helical
coil. Inner and outer coils are alternately joined together with
four cables at a predetermined spacing. Type II barbed tape is
the only barbed obstacle having a top and bottom. The bottom
is located mid distance between the shorter pair of spacer
cables. See Fig. 4.

diameter cable, located in the outer position of the arm will
support coils deployed at the top of the fence. Barb arms are
positioned so that the arms are out of reach from the approach
side of the obstacle.
6.3.2.1 Deployment—Stretch the coil out and locate the coil
loops uniformly as predetermined by the four spacer cables.
Rotate the entire coil assembly approximately 45°; positioning
the bottom, mid way between the tension wire and top of the
fence fabric. Inner and outer coil spacings are fixed at 24 in.
The alternating offset spacing between the inner and outer coils
is 12 in. o.c. at the bottom of the obstacle.
6.3.2.2 Tie Points—Before making the final attachment to
the fence, inspect the coils for tangles and proper coil spacing.
The inner and outer coils shall be securely attached in two
locations: one to the barbed wire, tension wire or cable located
in the barb arm and the other to the top of the fence fabric. See
Fig. 5. For installations using “V” arms; a second row of
barbed tape shall be installed to prevent using the arm as a
breaching aid. To reduce distortion as a result of adverse
weather conditions, spacer cables shall remain tight throughout
