Ballast frame helps to secure and safe Tower 1 system if it is not attached to the stage structure. It can hold up to 2000 kg of ballast and thanks to its design it can be easily attached to the Tower 1 base. There is also a pair of fixing points to which shackles or snap hooks can be placed and thus the ballast secured by ropes and slings etc. It is great for stacking and makes your rigging life easier.
