This Desmond DRBG Weight Bag for Tripods is an adjustable anchor bag designed to increase the weight of virtually any tripod for added stability. Offering a 44 lb load capacity, it can be filled with rocks, sand, or other location-handy materials to provide a lower center of gravity when using a heavy camera or large lens. Made of durable nylon, the bag is easily attached to almost any tripod and provides a built-in hook for suspending even more weight below it.
