Reliable Clip Test Leads — durable PVC jacket with copper conductors and serrated jaws for stable electrical connections Key benefits Durable construction: High-quality PVC insulation and copper conductors resist wear and give long service life for repeated testing and temporary connections. Safe to use: PVC insulation reduces risk of accidental contact during measurements and handling. Consistent, low-resistance contact: Copper conductors provide good electrical conductivity for accurate, repeatable readings. Secure grip on terminals: Serrated jaws and a ~10 mm clip opening clamp firmly to wires, posts and terminals to minimize slipping and maintain a stable connection during work. Broad compatibility: Designed to fit a range of terminal sizes and contact points, making them suitable for household electronics and automotive circuits. Features and performance Materials: PVC insulation with copper conductor. Clip opening: Approximately 10 mm — large enough for many wire ends, terminals and small posts. Jaw design: Serrated teeth for improved mechanical hold on wires and clamps. Typical uses: Test leads for multimeters, temporary jump connections, and secure attachments for repairs and diagnostics. Practical use scenarios Automotive diagnostics: Clamp to battery posts, sensor terminals or wiring harnesses to measure voltage and continuity without slipping during engine bay work. Home electronics repair: Attach to PCB test points, component leads or connector pins to take steady voltage or continuity readings while you probe or solder. Bench testing and prototyping: Create temporary circuits, connect components or hold wires securely during troubleshooting or component swaps. What you get A pair of clip test leads built with PVC insulation and copper conductors, serrated jaws for secure hold, and an approximate 10 mm clip opening suitable for household and automotive electrical tasks.
