SAFETYING – MAINTENANCE PRACTICES
Double-wrap method
The method of double-wrap safetying is shown on fig. 14, methods A and B, and uses
two separate lengths of wire.
Procedure
Run one end of the wire through the hole in the barrel of the turnbuckle and bend the
ends of the wire toward opposite ends of the turnbuckle.
Pass the second length of the wire into the hole in the barrel and bend the ends along
the barrel on the side opposite the first. Spiral the two wires in opposite directions
around the barrel to cross each other twice between the center hole and the ends.
Then pass the wires at the end of the turnbuckle in opposite directions through the
hole in the turnbuckle eyes or between the jaws of the turnbuckle fork, as applicable,
laying one wire along the barrel and wrapping the other at least four times around the
shank of the turnbuckle and binding the laid wires in place before cutting the wrapped
wire off.
Wrap the remaining length of safety wire at least four turns around the shank and cut it
off. Repeat the procedure at the opposite end of the turnbuckle.
When a swaged terminal is being safetied, pass the ends of both wires through the hole
provided in the terminal for this purpose and wrap both ends around the shank as
previously described. If the hole is not large enough to allow passage of both wires,
pass the wire through the hole and loop it over the free end of the other wire, and then
wrap both ends around the shank as previously described.
