Genuine REED replacement red alligator clip built for the R5002 high-voltage insulation tester. Like its color-coded counterparts, it uses toothed jaws (about a 1-inch opening, roughly 3.9 inches long overall) to clamp firmly onto test wires. It is rated 1000V/10A with CAT III 1000V and CAT IV 600V safety ratings, and includes a one-year manufacturer warranty.
