Using Plastic Strapping Tensioners

Pull the strap snugly around the package, taking care to keep the strap straight. Tuck one end of the strapping under the other end.

Squeeze the handle of the tensioner down to the base. Move the tool onto the strap.The end of the strap slides between the base and the gripper foot and extends 4 inches beyond the tool. Clamp down on the strap by releasing the handle.

Slide the back strap end through the cutter housing and the windlass.

Attach a seal to both the front and back pieces of strapping in front of the tool. Move the handle up and down to tighten the strap.

After crimping the seal with a strap sealer, press the handle down to cut the strap. Slide the tool away from the strapping. Discard leftover strap.


  • Use strapping recommended for your tensioner only. Don't bring the handle all the way back down while tensioning. Doing so releases the tension. Review and follow the operating and safety instructions for your tensioner.


  • Unsafe use may result in severe injury or death. Tighten the straps moderately. Too much tension can cause straps to break, causing injury. Keep fingers away from the cutter and the handle.
