The jaw opens to 2 inches of capacity and locks into any of 25 positions using a self-locking box joint — no slipping under load. The serrated jaw is machined from chrome vanadium steel and oil-hardened at multiple stages for long service life. Overall length sits at 9.9 inches, keeping the tool manageable in tight spaces. The plastic handle provides insulation from vibration. At 0.74 pounds, it handles daily carry without fatigue.\u003c\/p\u003e\n\u003cp\u003eThis plier is suited for residential and light commercial plumbing, HVAC, and mechanical work. The 25-position quick-adjust mechanism allows fast sizing changes when moving between pipe diameters, fittings, or hardware. The box joint design resists racking under torque, making it a practical choice for pipe work, conduit fittings, and general mechanical assembly. Licensed plumbers, HVAC technicians, and pipefitters are the primary users. The DIN ISO 8976 standard compliance ensures the tool meets international dimensional and performance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch jaw opening capacity with 25 locking positions for fast, precise adjustment\u003c\/li\u003e\n  \u003cli\u003eSelf-locking and reliable-locking box joint resists slipping under load\u003c\/li\u003e\n  \u003cli\u003eChrome vanadium steel jaw, multi-stage oil-hardened for durability\u003c\/li\u003e\n  \u003cli\u003eSerrated jaw face for secure grip on pipe, fittings, and hardware\u003c\/li\u003e\n  \u003cli\u003ePlastic handle reduces vibration transfer during use\u003c\/li\u003e\n  \u003cli\u003eMeets DIN ISO 8976 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard tongue and groove plier for general-purpose mechanical, plumbing, and HVAC service applications requiring up to 2 inches of jaw capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by licensed plumbers, HVAC technicians, and electricians for gripping, tightening, and loosening fittings and hardware. Always verify the jaw is fully locked into a position before applying torque to prevent jaw slip.
