The easiest way to hang signs, artwork, decorations, posters and more from your grid ceiling. Each Grid Clip Kit includes a twist on clip with a 48" string plus clothespin. The clothespin eliminates tying strings to signs, and height adjustments are easy. Use the put-up tool with your threaded broom or extension pole to prevent standing on chairs, desks or ladders, or attach the hangers by hand. Designed for suspended grid ceilings, will not damage tiles.
