After spending an hour installing the fixture, I find the glass component will not stay affixed as designed. Am returning

I love the looks of the sconce. It has nice clean lines. I have not had it installed as of yet. My handyman comes next week.

Fine. Waiting to install.

These lights were bought to replace an older worn out pair of the same lights. One of the shades was broken, and I had to use the glass shades from the old lights instead. The light itself was somewhat dirty so I think someone had maybe broken it and sent it back.
