Satco80-1389 Black Phenolic Ring, Uno Ring, 1-5/16" Inner, 2-1/8" Outer Diameter, cULus - Listed

Product was as described, I just couldn't measure exact diameter of my socket rings... which turns out to be 1-1/4 inches not 1-5/16. Think of it this way, the difference between 1/4 inch and 5/16 inch is like 4/16 to 5/16, so 1/16 of an inch or 1.27 mm, split on a radius of a circumference that is 0.6 mm or 0.5/16 inch. That is how accurate I had to measure it. Why am I not returning it? Because my smart ass came up with a way to compensate for the difference - rolled up some aluminum foil and it fits perfectly! The piece does not come in contact with heat nor electricity and since it is plastic being screwed onto plastic, I figured a way to make it work! I am thankful to this seller for actually even having an item close to what I needed. I browsed the WHOLE web for this piece and they are the only ones that have it!

I have two bridge lamps with Uno sockets that I wanted to use non-threaded shades on without having them wobble. By screwing one threaded ring onto the socket, then the lampshade ring and then screwing on the second threaded ring I was able to affix the shade firmly between the two rings and keep it from wobbling. Each socket only comes with one ring and extras are not readily available in my area, so I was very pleased to find these on-line.

These worked well enough. Nothing screwed into anything, but I put one on the bulb receptacle, then added the shade with it's metal ring that fits around the base of where the bulb screws in, then screwed in the bulb. It isn't perfect but does the job OK, and has helped keep the shade from moving around and going crooked.

Too small for my lamp. I bought it because several reviews said it was too big for their lamps and anything I was finding was too small for mine so I took a chance. Fail. Now I have three that are too small.

I have been looking for this size of ring for some time. I was glad I was able to find it on Amazon. They are just what I needed. They are the perfect fit.

Unfortunately these rings did not fit around the base of my bulb floor lamp.. Perhaps that's my fault, but I don't recall reading any measurement so I assumed it was a standard thread size. Plus, one of the two rings, which were packaged together, was broke. Guess I'm saying this particular purchase was a waste of money, so they went into the trash.1 star for delivery and1 star for being delivered on time.

It was perfect made my lamp look more beautiful it does not flop stays in place that’s what I needed

This little part helped me to turn an outdated lamp into a more traditional one. I would have had to get rid of the lamps, but now I can use them again.
