I wouldn't order from this site. Their specifications are far from specific. I ordered glass lamp shades that indicated a 1 3/4" fitting, which should have fit on my fixtures of 1 1/2 ". The dimensions were OD or outer dimensions not ID or inner dimensions. They charged me 27.95 to ship 6 glass shades. It took me 4 days to finally get an answer regarding returning them and the owner made a great show of saying my email was on his desk and he was just getting ready to call me. They charge a 20% restocking fee, so after a total of 123.46 for the shipping and the shades, I will still be out approximately $60.00 because he so generously said he would only charge me a 10% restocking fee. (insert sarcasm). I am very disgusted. Think I'll just sell these myself.
