This Automatic Clamp is made from chrome molybdenum steel for excellent durability. The shape of the clamp allows reaching into places where ordinary clamps cannot be used. The patented design means that it can automatically lock on any size without adjusting. The Set & Forgetâ„¢ feature enables the clamp to be set at a desired tip pressure for the job - slight to extreme - and the jaws adjust automatically. The handles are 15% thinner for easier grip and more power and are ergonomically designed for comfortable use. The re-engineered easy squeeze release lever ensures a controlled release with no pinch flare.
