The Knipex 87 01 250 Cobra is a 10-inch high-tech water pump plier featuring 25 fine adjustment positions via a push-button mechanism for rapid adaptation on workpieces. It utilizes a self-locking jaw design with hardened teeth to provide superior grip on pipes up to 2 inches and nuts up to 46 mm with minimal hand force. Ideal for professional plumbers and mechanics needing versatile gripping in maintenance and automotive repair.
The Channellock 424 is a compact, 4.5-inch straight jaw tongue-and-groove plier designed for precise gripping in tight spaces. It features a PermaLock fastener and laser-hardened teeth, making it ideal for small-scale mechanical and plumbing tasks. However, its limited jaw capacity makes it unsuitable for larger objects or heavy-duty work.
