To seize the knot, when seizing wire is available, insert a 6- to 8-inch length of seizing
wire through the center of the square knot and tighten the knot (A, in Figure 2-4). Bend the seizing wire
at its center. Use half the wire for wrapping to the right. Take several close turns with the seizing wire,
both to the left and to the right behind the square knot (B, in Figure 2-4). Cut the excess ends of the
conductor flush with the insulation. Continue the seizing wire wrap, to the left and to the right of the
square knot, until two turns are taken on the insulation. Cut the ends of the seizing wire and press them
down into the insulation (C, in Figure 2-4).
Figure 2-4. Square knot with seizing wire.
When seizing wire is not available, use the copper strands of the conductor to seize the
square knot. After the knot has been tied and pulled tight, remove the insulation from the end and
separate the three steel strands from the four copper strands (A, in Figure 2-5). (Copper strands will
remain bent when flexed.) Cut the steel strands flush with the ends of the insulation (B, in Figure 2-5).
Form an "X" over the square knot with copper strands. Cross the left-hand end of the copper strands to
the back of the knot, take it down under and bring it up from lower left to upper right (C, in Figure 2-5).
