GRS artificial grass pins are also an ideal tool for the installer of artificial grass. The thin pins allow the Artificial Grass Membrane to be fixed easily and temporarily. Ideal when it is windy or rainy. The seam tape can also be secured using the GRS artificial grass pins. The pins are easy to pull off again because of the large button on the oven side and thus easy to reuse. This also makes it a perfect tool for marking out lines on sports fields.
