Key specifications

Drive sizes, lengths and weights are manufacturer-stated (Ko-ken catalogue 2025-26).

Selecting the right option

Match the drive size to your sockets, and choose the length for the leverage you need and the room you have to swing the handle. The catalogue notes that 4768-450 and 8768-1000 have 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 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.
