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: a longer ratchet gives more leverage and a shorter one fits tighter spaces. 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.
