Method 1
Using a length of soft annealed wire, place one end in the
groove between two strands of the wire rope. Turn the long
end of the annealed wire at right angles to the wire and wrap
it tightly over the portion in the groove.
The two ends of the annealed wire should be twisted
together tightly. Cut off the excess wire and pound the twist
flat against the wire rope (Figure 1-11).
Method 2
Wind a length of soft annealed wire around the wire rope at
least seven times. Twist the two ends together in the center
of the seizing. Tighten the seizing by alternately prying and
twisting. Cut off both ends of the wire and pound the twist flat
against the rope (Figure 1-12).
NOTE: Non-preformed wire rope should have two seizings
located on each side of the cut (Figure 1-13).
