Common specifications

Key specifications

Weights are manufacturer-stated (Ko-ken catalogue 2025-26).

Selecting the right option

Match the drive size to your sockets and extension bars, and choose the length to suit the room you have to swing the handle. Reversible ratchets with a quick release button have less strength than a normal ratchet because of the technical design, so use the ratchet correctly. (manufacturer-stated) Ko-ken's catalogue safety notes say that a ratchet is not a hammer, that loose pipes or other improvised attachments should not be added to handles for extra leverage, and that plastic or rubber handles are not intended to act as insulation.
