Sorry I don’t have information on the brand for these. We were fairly broke when we bought them, so I expect they are from either The Home Depot or Lowes. I will let you know if I can dig that information up. We had these bare wood doors installed (along with the new stainless hardware) two or three years after we bought our home (we bought the home in February of 2007.)

For those new to this website:
Tamara Rubin is a multiple-Federal-award-winning independent advocate for consumer goods safety and a documentary filmmaker. She is also a mother of Lead-poisoned children. Tamara’s sons were acutely Lead-poisoned in August of 2005. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. Tamara uses XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals), including Lead, Cadmium, Mercury, Antimony, and Arsenic. All test results reported on this website are science-based, accurate, and replicable. Items (and separate components) are each tested multiple times, to confirm the test results for each component tested and reported on. Please click through to this link to learn more about the testing methodology used for the test results discussed and reported on this website.
What about your door hinges?
We have door hinges made of stainless as well.
