Even electricians need ratchets, but when you’re working with high-voltage, you can never be too careful. That’s why Kinpex makes both 3/8″ and 1/2″ drive insulated ratchets along with insulated extensions and sockets in both SAE and metric sizes.
Rated for 1,000V, Knipex covers these chrome vanadium ratchets with insulation that meets DIN EN/IEC 60900:2004 standards. The ratchets reverse for both clockwise and counter-clockwise operation, and they feature an extremely smooth ratcheting action.
These insulated tools don’t come cheap. Expect to pay $120 to $150 for the ratchets alone. If you want a ten-piece set including the ratchet, two extensions, and seven sockets, expect to part with $500.
