Knipex 87 21 300 Cobra® QuickSet High-Tech Pliers – 12" (300mm)

Fully Open, Push, Grab. Instant Sliding Adjustment. Industrial-Scale Gripping Power.

The Knipex 87 21 300 Cobra® QuickSet takes the world’s best water pump pliers and adds a "sliding" function for unmatched speed on the jobsite. This 12-inch industrial model features a unique spring-loaded hinge bolt that allows you to simply slide the lower jaw directly onto the workpiece. There is no need to press the button while closing—just open the pliers fully, position the top jaw, and slide the handle up to the workpiece for an instant, rock-solid lock.

For the professional at The Fastener Group, the 12-inch QuickSet is a game-changer for high-torque tasks in confined spaces. With a massive 2 3/4" (70mm) capacity, it handles large pipes and nuts with ease. The patented self-locking jaw geometry ensures that once the first workload is applied, the pliers bite down and won't slip, allowing you to focus 100% of your energy on turning the fastener rather than squeezing the handles.

Key Features & Professional Benefits:

• Rapid QuickSet Adjustment: Combines the reliable locking of a push-button hinge with an additional sliding function. Just slide the handle directly onto the workpiece for the fastest setup in the industry.
• Massive Industrial Capacity: Offers a wide 2 3/4" (70mm) gripping width for pipes and a 2 3/8" (60mm) capacity for nuts, outperforming standard 10-inch pliers.
• Self-Locking Efficiency: Specialized induction-hardened teeth (61 HRC) bite onto pipes and nuts automatically. No handle-squeezing is required to maintain a secure grip, reducing hand fatigue.
• 25-Position Fine Adjustment: Allows for optimum adaptation to different workpiece sizes while keeping the handle width ergonomic and "hand-friendly."
• Box-Joint Stability: The double-guided design provides high stability and prevents the pliers from twisting or "walking" even under the most extreme industrial loads.
• Safe & Durable Construction: Forged from chrome vanadium electric steel and multi-stage oil-hardened. Features a pinch guard to protect your fingers from accidental crushing.
• Confined Space Specialist: The slim head design and rapid sliding adjustment make this the ideal tool for working in tight machinery bays and plumbing chases.
