We're trying to install a chandelier and the instructions are generic (not for this specific light). I have hung chandeliers before but they always utilize the center threaded piece that holds the weight of the fixture. This one came with a wire cable. How do I attach this? Should I loop it through the mounting bracket? I installed it without using the cable and then couldn't sleep as I imagined the chandelier crashing to the ground. It was only being held up by the decorative screws on the canopy. Is that enough?
