After the deadbolt on my very old front door in my very old house failed, I was at a loss to find a replacement that would be both attractive and fit the diameter of the hole in the door. I was surprised to learn that there were almost no options. I was also relieved when I found that Schlage had a solution. The quality of this deadbolt is an aesthetic upgrade, easy to use, and best of all, easy to install even in a 100+ year old front door. I already know that the quality is excellent from other Schlage products I have in the house. I am happy to recommend this product.
