We were replacing cabinet hardware the previous owners had installed and painted which looked very bad. In order to cover the 'footprint' we used the backplate AME-17138 with the handle AME-13935. They look so sharp as the curve of the handle perfectly matches the curve of the backplate. I highly recommend using the two together.
We have lived in the house for seven years and just never paid much attention to the existing cabinet knobs until replacing the old green Formica countertops and backsplash. Most of the appliances have been updated to ones with stainless finish so the old brass knobs seemed to really stand out after the new work. We installed the Amerock Inspriations Satin Nickel knobs and it is incredible what a difference it made in the finished product. This small detail was the last element required to coordinate all the upgrades, looks like a new kithen.
