Description

These Cast Brass Highbox flanges were made by Kohler back in the 1980’s for their hightank toilets.  Kohler was unusual in that they used a 2″ flush tube where everyone else used a 1 1/2″ tube.  Kohler used these to hide both the spud and the nuts at the bottom of the tank.  These are held onto the tube with a set screw.  The flange is 2 1/8″ tall overall, and depth of flange is 1 5/8″.  Width of flange is 3 1/2″.  Limited availability!
