The worst possible design for installing the shades. A normal sized hand will not fit up into the fixture to screw in the clip holding the shade it place. And the threads on the individual light mountings re cast from a "stone" like material instead if the usual metal making it impossible to screw on the shade even if your hands fit in. A totally worthless product. Was generously replaced by Wayfair but the second unit had the same issues. DO NOT ORDER THIS LIGHT  there are better products.
