These Ground Markers, Ground Sockets are made of strong but flexible plastic. Install these sockets in various reference points ( intersections of lines ) of your athletic fields. With these sockets in the ground, you will never have to remeasure your fields to lay out your paint lines. If the paint lines  fade because of mowing between weekly games you will not have to go through the stress of eye-balling the old lines and hope you get straight lines.

Just run a string from one socket to another and striping your athletic fields becomes a breeze. Beginning of next season save hours laying out fields, just run your string from one ground socket to the other.Click on RHS icons for more information on how to use these ground sockets on various types athletic fields.
