Several types of ties can be used with rebar. Some are more effective than others. The views in Figure 42 illustrate the six types used by the Seabees: (A) snap, or simple, tie, (B) wall tie, (C) double strand tie, (D) saddle tie, (E) saddle tie with twist, and (F) cross, or figure eight, tie. As a Builder, you will probably be concerned only with the snap and saddle ties. As a professional, you should be familiar with all six types.

To use the snap, or simple, tie (View A), simply wrap it once around the two crossing bars in a diagonal manner with the two ends on top. Then twist the ends together with a pair of side cutters until they are very tight against the bars. Finally, cut off the loose ends. This tie is used mostly on floor slabs.
To make the wall tie (View B), take one and one half turns around the vertical bar, then one turn diagonally around the intersection. Twist the two ends together until the connection is tight, then cut off the excess. The wall tie is used on light vertical mats of steel.
The double strand tie (View C) is a variation of the simple tie. It is favored in some localities and is especially used for heavy work.
Pass the wires of the saddle tie (View D) halfway around one of the bars on either side of the crossing bar and bring them squarely or diagonally around the crossing bar. Then twist the ends together and cut them off.
The saddle tie with twist (View E) is a variation of the saddle tie. Carry the tie wire completely around one of the bars, then squarely across and halfway around the other, either side of the crossing bars, and finally bring the ends together and twist them either squarely or diagonally across. The saddle tie with twist is used for heavy mats that are to be lifted by crane.
The cross, or figure eight, tie (View F) has the advantage of causing little or no twist in the bars.
