Stackable Banana Plugs to Test Hook LeadsThe stackable banana plugs are pass-through style so you can plug in another set of leads and have two active pairs of leads at the same time. This allows you to quickly use another style of wire without having to re-insert or re-plug the wires. When you need a third hand, or need to test many circuits in a row, this is an absolute necessity. Copper Alligator Clip LeadsThe test leads have solid copper alligator clips on both ends. The maximum width of the alligator clip opening is 10 mm. Lead length: 39.37 inches. Voltage: 1000V. Current: 15A. Sturdy Alligator Clips with Leads: The alligator clips are securely fastened to the wires and the rubber insulation ensures that they won't slip out of place when in use. The springs on the alligator clips are strong enough to keep them from deforming after a lot of use. Banana Plug LeadsRugged banana plugs and silicone insulation greatly improve the durability and flexibility of the leads, preventing the "memory" properties of plastic insulation after being coiled/wrapped for a period of time. The plug fits well into other leads and test sockets and serves to extend the operating distance. Essential Multimeter Test Lead KitsThe 10-piece test lead kit is perfect for all electrical testing, electronic applications such as automotive parts, and circuit testing of classic cars, trucks and motorcycles. As long as you are testing 15A or smaller fuses.
