Campaign Towel BarSturdy and elegant, our Campaign Towel Bars are perfect for your kitchen, island, or bathroom. The rails are made with 3 4" solid brass tubing. Each end of the brass tubing is internally threaded to accept a rail connector for extending its length. Middle brackets hide seams when using a rail connector to extend its length. For a custom fit, the rails can be easily cut to length by a capable DIYer or tradesperson. Individual components are also sold
