Purpose of the frames is to support the tanks so that one or more tanks can be stored at the same location. The frames are necessary as the tanks are round-shaped and therefore can’t stand on their own. Up to three tanks can be supported by one frame. All frames are produced in our own workshop and consist out of the best possible materials.
• Frame 1A: one tank on four legs
• Frame 2A: two tanks vertically stacked on each other
• Frame 3A: Three tanks, stacked as a pyramid
• Frame 3AA: Three tanks stacked vertically
