The compact selector is WihaŽs smart solution for any craftsman who only has one free hand to remove and change bits while working. The new single-hand bit box makes bit removal and attachment a super easy. The red slider allows bits to be removed in the blink of an eye. The trick is that the bits are pushed out of the box "backwards" and can be attached directly to a tool. In the past, you had to set down the driver and open the box. This is not the case with the new selector. One hand does it all. In addition to saving valuable time, this reduces the risk of accidents when working on ladders.
