Fol-Da-Tank Flange options for the Rol-Tank-Tank product line.  When no longer in use, the tank water may be quickly drained through a flange coupling on the side. 

All self-supporting tanks have reinforced heat sealed patches around the aluminum flange.  The flanges are made from high quality al-mag alloy which provides top quality castings and threads.

Flanges range from 1.5″ – 3″ with standard NST male or female threads available.
