Rigging Accessories Sandbags have long been used for a variety of stage purposes; most often as a portable and adjustable counterweight method for hemp rigging. Sandbags are also frequently used to weight floor plates for stage bracing and to secure scenery or props. These sandbags, made in the U.S.A., are carefully rated for the weight of sand they will hold. They are made from #8 natural cotton duck canvas, reinforced with a sling, and equipped with a drop forged steel 750 lb. rated hook and safety catch. Sand is not included.
