Antique Doorknob Collectors of America
Your support helps preserve the history of antique hardware and keeps the ADCA community thriving for collectors of every generation.
The Antique Doorknob Collectors of America has developed this website as a virtual photographic museum, which seeks to catalog every antique doorknob and the related hardware which exists today. This site benefits individuals, businesses, and organizations who collect antique hardware, buy, sell and trade it, and who study and appreciate the artistry of the designers, sculptors, architects and crafts people who created useful works of art for homes, offices, factories, schools, churches and public buildings across America and the rest of the world. People like you.
Your support of this site is essential, since the Antique Doorknob Collectors of America is a non-profit 501(c)(3) organization devoted to the study and preservation of ornamental hardware. Your contribution to support the development of this website, the continuing expansion of knobs and information shown, and the development of additional features by the ADCA would greatly benefit all of our current and future users and members. Donations to the ADCA for our educational purposes are generally tax-deductible for the donor.
