Shank extensions

Extension

— an additional device designed, in accordance with the name, to increase the working length of a wrench or ratchet. It has the form of a rigid or flexible axis, one end of which is attached to a wrench / ratchet, and a working nozzle (for example, a socket head) is put on the other. Extension cords are indispensable when working in hard-to-reach places that cannot be reached with ordinary tools. Their length can be different, the same applies to the format of "seats" for working nozzles; these points in each case should be clarified separately.
