Question: May be a silly question, but do you have to buy 2 for each door?
Document: Big big fan of these. We have received numerous complements. They totally transformed the interior of our house. Don't forget to buy matching hinges.
I have replaced all of the door levers in my home and am very happy. I think these are beautiful and they seem very well made.
I replaced all of my door hardware throughout my condo with the Baldwin &#34;Madrina&#34; line. It is a really beautiful and simple upgrade. I installed it all myself and each one probably took about 15 minutes. Very little effort required but it has made a really great design impact.
Very well constructed. Heavy duty. Very nice finish and easy to install. Home improvement stores sell them for 10-20 dollars more.
Very good quality by Baldwin. They used to sell them at Home Depot, but HD is not carrying the higher end Baldwin any longer. Too bad. I was glad to be able to get them thru Amazon. Priced right I would say.
Not a lot more expensive that Schlage & Kwikset, but oh so much better in the way it looks and works, smooth, and doors just close easily with a quiet click. Bought 10 for our house and another 15 for our cabin.
Baldwin has had a great reputation for quality. The product remains a quality product. Very easy to install - they install either right or left hand.
