This ½” square aluminium pole is used as a shelf support pole, very similar to a 1009.
The pole is best used when supporting three or more shelves. Unlike the 1009 shelf support pole, the 117 pole comes as one piece and is also shorter.
It can be cut down if necessary to fit into small spaces where height is a problem, using a hacksaw.
The pole does NOT come with end caps or pole clips. You must order these separately.
