Splicing It
Cut off, or out, the damaged
wire and tie the two ends of the
wire with a single knot leaving
about six inches of wire on
either end of the knot. The knot
will take the strain off the line at
the point you make the splice.
If you are using the splice kit,
splice the ends and wrap the
splice with insulation tape.
If you’re using the U1R, split
each pair of conductors and
insert them into the splice. Make
sure the conductors go through
the metal prongs and all the way
to the center of the U1R.
Center the U1R in the
crimper. Press firmly until the
red top part of the U1R is even
with the clear bottom part. No
tape is needed because the insu-
lating grease in the splice pro-
tects against electrical leakage
and corrosion. The insulating
grease also makes the splice
waterproof.
When you turn in used wire, your DRMO will probably want it cut up and turned
in by the pound. Check with them to make sure.
One mile of WD-1 wire weighs about 48 pounds. WD-1A is a little lighter at
about 38 pounds. WF-16 is heavier at 62 pounds per mile of wire.

More than
four splices
in any 1/2 mile
of wire means
it can be used
for
training
only.
it’s ready for
disposal if you
don’t need it
for training.
Tie ends with
a single knot
Insert
conductors
in U1R
Center U1R in crimper
and squeeze
The number of
the splices and
the resistance of
the wire tells
you the wire’s
condition.
Four
or
fewer
splices in 1/2 mile of
wire is OK for mission
use as long as the
electrical resistance
checks out. If you’re
using WD-1 or -1A,
the resistance should
not exceed 241 ohms
per loop mile at 70°F.
If you’re using WF-16,
282 ohms per loop
mile should not be
exceeded.
Finally, every
commo soldier
worth his boots
takes care of
his wire by the
book…
