"?Q: I have an older house, built in 1950, and all the interior doors have smaller doorknobs than most. The holes in the doors are between about 1 1/2 to 1 3/4 inches. Do you have any knobs that would fit these doors? I have been having a difficult time finding them, and drilling new, bigger holes to accomadate most new Door Knobs has proven difficult. Please advise. A: This puts you in a tough position. There are not a great deal of knobs to choose from that will accomodate the bore hole size that you have indicated. I wish we could help you on this one, but most door hardware manufacturers use the standard 2 1/8? bore hole. You may try searching for restoration hardware, or see if you can find some antiques in good condition. Sorry I can't be of more help."
