Durable alligator clip test leads built for reliable, safe connections during electrical repairs and tests. Key benefits Reliable performance: Copper conductors provide consistent electrical contact so measurements and temporary connections stay accurate. Safe insulation: PVC coating improves user protection and reduces risk of accidental shorts during use. Secure grip: Serrated jaws clamp firmly onto wires and terminals, preventing slipping and keeping connections stable while you work. Universal fit: Approximately 10 mm clip opening fits a wide range of terminals for household electronics and automotive applications. What makes these clips useful Materials chosen for durability and conductivity: PVC insulation for safety and copper conductors for good electrical flow. Positive mechanical design: The serrated, toothed jaws hold components securely without constant manual adjustment. Practical size: The ~10 mm opening balances accessibility and hold for common terminals and wire sizes. Practical use scenarios Automotive diagnostics: Clip to battery posts, fuse terminals, or sensor leads while troubleshooting charging and starting systems. Home appliance repair: Attach to switch terminals, connectors, or transformer leads during testing or temporary replacements. Electronics testing and prototyping: Make temporary connections to circuit boards, test points, or multimeter probes during measurements and adjustments. Specifications Materials: PVC insulation, copper conductors Clip opening: Approximately 10 mm Jaw type: Serrated (toothed) for secure grip These clip test leads provide a straightforward, safe, and dependable way to make temporary electrical connections for repair, testing, and diagnostic work.
