Proline field layout system makes it easy to permanently locate key measurements for any sports field eliminating repetitive measurements. Once in place, simply connect the guide string to the markers and begin striping. Anchors for guide string are built in to the markers so they can't get lost. If marked lines become too faded to follow for re-striping, the locators are still in place. Just restring the particular area, and your marked lines are relocated exactly. additional markers available in 6 and 10 piece sets can be used to locate inbound lines, coaches' boxes, penalty areas and more. All sets include locators, starter tool 600' roll of cord.
