Designed for solo use, it gives you controlled leverage and accurate positioning without needing an extra set of hands.

  • Purpose-built to prevent injury from improper installations

How It Performs on the Job

Real-world use is where this kit shines. The tool grips securely and gives you the reach and angle needed to position O-rings safely - even when working solo. Compared to using clamps or makeshift leverage tools, it’s cleaner, faster, and far less stressful on your hands and shoulders.
