The MIL-L-1709 specification covers tent lines used in tentage, tarpaulins and covers.
For Class A examples in military parts documentation, the line is specified as manila rope in multiple MIL-L-1709 configurations.
Typical applications
tent ridge and guy lines,
temporary shelter anchoring,
tarpaulin and cover restraint,
field-equipment line assemblies.
This record is therefore treated as a tent-line specification rather than a life-safety or rescue-line specification.
