— a specific type of extension that is installed between the tool and the replaceable nozzle. The universal joint allows you to deflect this nozzle at a certain angle, which is useful when working in difficult conditions. In fact, this device is a compromise between a flexible and a rigid extension (see the relevant paragraph): it does not give such freedom of movement as a flexible extension, but it allows you to work with greater efforts, which is comparable to the capabilities of rigid devices.
