Lamp Chimneys are a bulbous shape known as "Wiena Bulge". This clear chimney has a smaller fitter to use on Gem Arctic and #0 Hornet burners.
5 star service getting me a globe for an old lamp. First one did not fit, but they promptly sent a globe that is just right. Well done.
This item shipped quickly and was packed in such a way that it would be very difficult to break it during shipping. I was very pleased with the product.
These are high quality at a reasonable price. My only concern is that they are relatively fragile so be careful will installing them.
Good fit for sconces whose originals had disappeared.
