Dimensions: 1-1/4" Diameter x 15" Long. Please note that, unlike our regular #137 (unfinished), this one does not have a tenon. Instead of a tenon, it has a 3/16" machine screw installed. The machine screw protrudes about 1/2". All you need is a bolt to install it on your paper towel holder base! Milled from Maple, varnished.
