This LuxS 10kg Filled Counter Balance Sandbag comes with four 2.5kg ready-filled weight pouches, and can be used in a variety of ways. These include adding weight to your light on your pantograph, adding stability to a tripod or light stand, or counter-balancing a boom arm. The four pre-filled bags contain separate sealed sachets of safe marine-quality galvanised metal ballast, allowing you to adjust the weight from 2.5kg to 10kg. Strong plastic clips allow the handles to be wrapped around objects before they clip in place.
