Question: The one I have is 2 1/2 " at the "fitter" end.  The twin Stiffel lamp needs a replacement and I would like some assurance that the ones you offer will
Document: I thought it was over for my Stiffel lamp when I tipped it over and its reflector shade shattered. Thanks to the wonder that is Amazon and thanks to FreeVermont, my lamp has new life! Package arrived safely and securely at the post office. Works like a charm. Thank you!
Things that go exactly like you expect are always hoped for, but seldom happen. This is one of those times where things worked out just as I hoped. I needed an 8" floor lamp, glass reflector. Upgradelights had this one at a reasonable price. The fitter size was right, the color and pattern were right, it looked like a perfect choice. I barely had the order placed when the Post Office carrier met me in my driveway with the box containing the reflector.
I broke the shade glass on an old torchiere lamp, and a replacement was not to be found in any store. So, I decided to check online  to see what was available. This one fit perfectly, and it is very solid. It's about 1/4 inch thick glass. It defuses the light beautifully ... I'm actually glad the original one broke. This one is much, much better. And, the price is right.
I didn't think I would be able to replace the shade to my vintage Stiffel floor lamp that unfortunately met with mishap. Since there are several sizes, measure carefully, preferably the old shade if you can put the pieces together long enough to do so. I didn't have the shade, but measured the guides in the harp and held the fabric shade high enough to get an idea of the height.
Movers broke the original shade of a lamp during a recent move. I was pleased to find this, and even more pleased to find it a perfect fit as a replacement. Now, I'm going to buy a second one. My wife broke this one last week. (sigh)
When my little granddaughter broke my floor lamp's glass globe, I was sure the lamp was now junk because I didn't think I'd be able to replace that shade - so very glad to find this online, it was packed with care so arrived in one piece, & fits beautifully. Thank you for offering these replacement glass shades! !
The shade was not common to most shopped stores, so I went to  &#34;amazon&#34; and in short order found what I thought would be the one. Had it shipped to my daughter in Nashville and it was there as requested, plus the fit was perfect. Great ordering experence!
I broke a lamp bowl last year and had trouble finding the right replacement. When I finally did find one through Amazon (not the one I am now reviewing), Amazon had to cancel the order because their inventory records incorrectly showed that they still had stock, when they did not. Although Amazon did not suggest an alternative third-party seller in its marketplace, I did find another seller (the one selling me this product) also through Amazon.
Had an old lamp that I loved and the reflector shade on it broke. This was a perfect replacement. Nice solid glass, just the right shade. Very pleased with the purchase.
Warily purchased this as we weren't sure it would fit on our lamp. Bingo! Exactly what we wanted. Unfortunately this stuff is made of glass and you can't whack it with a 2x4 and expect it to bounce when it hits the wood floor. Classy looking, saving our $ for another.
Answer: yes
