Tank Rings. Tank rings filled with gravel lift the tank above the surrounding grade. This keeps the tank out of standing water and increases the life of the tank bottom.
Easy to level and line up the rings in the tank battery. Angle iron bottom spokes will help self-level the ring with a few spins or rotations in the base sand or pea rock. Designed by oil industry field men for oil field service groups. Built with common sense and safety in mind.
