Snow rake with telescoping pole
A telescoping pole and blade to form a snow rake. The pole has a plurality of segments selectively axially movable relative to one another. The pole segments are keyed to one another to prevent relative rotation between adjacent pole segments. A lock device is associated with adjacent pairs of pole segments to selectively fix the relative axial positions of the pairs of pole segments.
