The Rosco 10 lb Sandbag (Empty) is a bag with the capacity to hold 10 lb (4.5 kg) of sand. It is a rigging accessory designed for stage purposes. Most often, it is used as a portable and adjustable counterweight method for hemp rigging. It's also frequently used to weight floor plates for stage bracing and to secure scenery and props. Made in the U.S.A, these bags are carefully rated for the weight of sand they can hold. Built out of strong canvas, reinforced with a sling, and equipped with a heavy metal hook and safety catch, these bags are sure to do the job. Sand is not included.
