Pistol grip banders are used to

• A. cut bands
• B. measure tension
• C. remove bands
• D. tighten bands

Answer: (D)

The main idea is that pistol grip banders are designed to apply tension to a strap so it cinches tightly around a load. When you squeeze the trigger, the tool pulls the band tighter, letting you secure insulation or bundles firmly before sealing. Cutting the band, removing it, or measuring tension aren’t accomplished by this tool; they’re done with other tools or steps. So tightening the band is what this tool is used for.
