The ground level ring is often used for fencing around sports fields and in combination with the retaining ring. The ring is placed around the upright to prevent weeds from growing directly around the post. The retaining ring is placed over the ground level ring and tightened with the Allen key screw. This fixes the ground level ring and also prevents the pole from sinking into the ground. The rings are available for 62 and 92 millimeters tubes and in the RAL colors 9005 black and 6009 green.
