Common specifications

Key specifications

Lengths and 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. The catalogue notes that 3726Z-280 has a longer handle than standard and can be loaded to excessive torque, so apply load evenly and progressively to avoid breakage and possible injury. (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.
