Pistol grip banders are used to

• A. straighten pipes
• B. test insulation
• C. mark positions
• D. tighten bands

Answer: (C)

Marking positions on pipes or insulation is what this tool is for. The pistol grip bander provides a quick, one-handed way to place visible marks at the spots where bands will be applied. By marking these locations, installers can maintain consistent band spacing and alignment, which helps the wrap stay neat and secure once the bands are installed. It’s not intended to straighten pipes, test insulation, or perform the tightening step—that work relies on other tools or functions. The mark created by this tool gives a precise reference point for subsequent wrapping and fastening.
