Calumet 4.5kg Sand Bag - Empty

These empty, woven nylon fabric bags can be filled, emptied and refilled with sand, shot, or gravel. Their saddlebag design features two compartments which can be easily filled and zipped up. Zip closures are protected with a secure hook and loop closure. Ideal as ballast for boom arms, or to weigh down lighting stands, reflector supports and background supports. Even photographic tripods will benefit from the vibration damping effect a sandbag provides.
