A variety of grades of filament tape are available. Some have as much as 600 pounds of tensile strength per inch of width (100 N/mm). Different types and grades of adhesive are also available. Most often, the tape is 12 mm (approx. 1/2 inch) to 24 mm (approx. 1 inch) wide, but it is also used in other widths.
The platen then drops and the hot knife is removed. After the hot knife is completely clear of the straps the platen comes back up and compresses the joint so that the melted portions of the strap mix and harden. For thicker plastic strap, usually 0.73 mm (0.029 in) and thicker, friction is used to create heat within the joint.
Filament tape or "strapping tape" has filaments (usually fiberglass) embedded into the adhesive for extra strength. Gaffer tape (or simply "gaff tape") is normally based on a heavy fabric or plastic tape. Hockey tape or "friction tape" is a somewhat rough cloth tape used for grip on hockey and lacrosse sticks.

The wire and 1 ⁄ 4 in (6.4 mm) of insulated wire are placed in a hole near the edge of the tool. The hole in the center of the tool is placed over the post. The tool is rapidly twisted. The result is that 1.5 to 2 turns of insulated wire are wrapped around the post, and above that, 7 to 9 turns of bare wire are wrapped around the post.
