Cable tie installation tools make cable tie application easier and safer. Doing the job with your bare hands adds undue amounts of stress on cables you are bundling, as well as unnecessary wear and tear on you.
The P-200 has adjustable bundle tension settings:
1) Lowest bundle tension
3) Highest bundle tension
Simply cinch the cable tie around items to desired bundle diameter. Insert exposed cable tie strap into the side of the P-200. Squeeze the trigger until the cable tie strap is cut off.
