Trapeze Rigging Indoor Rig?

Has anyone used this rig before? How do you like it? I was looking for getting an indoor rig with hammock for my daughter for Christmas and as congratulations for graduating from beginner aerial class to intermediate, but am unsure as to whether the indoor rig would be tall enough? She's 4 feet tall and practicing candy cane, holding on inverted by various points of her body, etc. I do not want her to practice any drops at home, though.
