The KUPO KSW-05 WRAP & GO shot bag with non-slip strap design allows you to weigh down light stands by just wrapping around the stand base. The premium shot bag made of 1000 denier black textured Nylon also offers a variety of uses including offsetting a boom arm, ballast for a tripod or light stand base or wrapped midway on a stand handle to offset the weight of something. The shot bag is pre-filled with 2mm steel shot balls to provide a dense counterweight. The shot bag is sealed at the factory so as to lever leak. The compact size design also makes the shot bag easy to carry, pack and does the perfect job.
