Grass, Turf and Athletic Field Hashmarker/Bordering box. The box is exactly 4 by 2 ft. It can be raised and lowered for perfectly clean hashmarks. Or you may choose to adjust the height of the box off the grass and just leave it up all the time. This is faster, with a little less effort. No stringing side lines needed, just follow the side line and use the 4 spacer for precise measuring.
