Fixture came with retaining rings screwed on to bases, for shipping. These had to be removed to install shades, but one ring was screwed on crooked and took 2 people and 2 tools to remove (gently as to not twist wires or bend base). Then to screw ring on inside shade I had to fit my hand inside. Now I'm a small woman, with average size hands, but I could barely get my hand in far enough to hold the ring with my fingertips. Can't imagine a typical male electrician being able to do this. Looks great tho. Easy to install. Good price.
