The Italgrass seam tensioner is also called a pull tensioner and is the older brother of the Italgrass knee tensioner. The Italgrass seam tensioner is also used for tensioning synthetic grass seams and to remove folds from synthetic grass, especially in large areas of synthetic grass (sport). The two tension knobs are each with fine and coarse teeth. The tension head is equipped with a special tension block, which makes the seam tensioner very effective. The Italgrass seam tensioner can also be used to place the synthetic grass seams against each other.
