This category includes wire ropes in sizes
as small as 1/32" in diameter. They're
used in a variety of applications, including
control cables, window and door closures, different
kinds of remote control systems, boat rigging
and many others.
They can be made of galvanized or stainless
steel wire.
Each of these products is carefully engineered
and fabricated to uniform size and quality.
For example,1/16" 7 x 19 contains 133 separate
wires, making the wires approximately the diameter
of a human hair. Yet the rope has high strength,
bendability and fatigue resistance.
These ropes are produced for the most common
applications in the market. Utility grade is
made to RR-W-410. These cables have historically
been called"aircraft" cable. Since
most applications do not require that designation,
we are changing the name to "utility"
cable. We can provide these ropes to MIL-DTL-
83420 "aircraft" specifications on
request. They require special lubrication during
manufacture, internal marking and fatigue testing.
