Gripping strength you can trust

Gripping surfaces feature special hardened teeth rated at about 61 HRC, which translates to a secure bite on pipes, nuts, and fittings. The teeth grip firmly even on slightly rounded surfaces, helping you complete adjustments with less slipping and rework. This combination of hardness and geometry supports consistent contact across a range of sizes.

• 61 HRC hardened teeth for durable bite
• Secure grip on pipes and nuts with minimal slip
• Works across a variety of fitting sizes

Self-locking design for reduced effort

The self-locking mechanism helps hold the workpiece in place, so you can apply steady pressure without losing control. This means you can tighten or loosen components with less overall hand force while maintaining precision, which is especially helpful during repetitive tasks or when space is tight.

• Self-locking on pipes and nuts for steadier work
• Lower handforce requirements without sacrificing control
• Resilient grip across common sizes and shapes

On-the-fly adjustment with the push button

Push the button to adjust the jaw size directly on the workpiece. The quick-change mechanism saves time and keeps you focused on the task at hand, whether you’re tightening a stubborn valve or reconfiguring a fitting in cramped spaces.

• Push-button jaw adjustment for fast sizing
• Smooth jaw movement with reliable positioning
• Ideal for confined work areas
