The relationship between a coat hanger and a hanging rod holds something of a fascination for us. It is something that goes largely unnoticed when functioning properly but is an unending source frustration when it is not. Two commonly troublesome factors that hamper the easy movement of a coat hanger along a rod are surface drag and improper rod thickness. In combating these we experiment with a new profiles for my closet rods from time to time, an example of which can be seen here in this small teak shelf with integrated hanging rod.
We have here eschewed the cylindrical closet pole in favor of one shaped like a rectangular prism with chamfers along all four edges. The quadruple chamfer creates in profile an elongated octagon, a nice form reminiscent of Gio Ponte's Pirelli Tower and New York's Pan Am/MetLife Building. This shape maximizes the weight-bearing thickness of the rod while keeping the width slender and well out of the way of any part of the hangers. The chamfers relieve the pressure from the edges and allow the hangers to slide freely.
