10-piece set of fully insulated black crocodile (alligator) clips designed for reliable test, measurement, and wiring work. Key benefits - Secure, low-resistance connections: copper contacts and a strong spring mechanism deliver consistent conductivity and a firm grip so signals and power remain stable during testing or assembly. - Safe and easy to use: fully insulated PA (polyamide) housings reduce the risk of accidental shorts while allowing clear access to the contact when needed. - Fast wiring and soldering: 4 mm cable hole accommodates common wire sizes, and a maximum jaw opening of 14 mm accepts terminals, bare conductors, and small connectors without fuss. - Broad compatibility: designed to mate with standard 4 mm banana-style connectors for quick integration with voltmeters, power supplies, probes, and battery clamps. Key specifications - Quantity: 10 clips (black) - Body material: PA (polyamide) insulation - Contact material: copper - Compatibility: fits 4 mm standard banana plugs - Maximum jaw opening: 14 mm - Cable hole diameter: 4 mm Practical applications - Electronic testing and bench work: attach clips to component leads, test points, or probe tips for hands-free measurements with multimeters and oscilloscopes. - Battery and power testing: connect to battery terminals, clip to supply rails, or link power packs to prototypes for quick, temporary power delivery during experiments or troubleshooting. - Prototyping and small wiring jobs: hold wires and connectors in place while soldering or assembling circuits; useful for R&D, classroom labs, and hobby projects. Why choose these clips - Reliable materials and mechanics: copper contacts for conductivity and PA insulation for durability and safety. - Versatile fit: compatible with common 4 mm banana systems and sized to handle a range of cables and terminals. - Ready for immediate use: set of 10 gives multiple connection points for multi-channel testing, parallel circuits, or spare parts on the bench. What you get - Ten fully insulated black crocodile clips with copper contacts, strong springs, 14 mm max jaw opening, and 4 mm cable holes — ready for testing, wiring, and prototyping tasks.
