A simple hardware swap-out can have huge impact on the appearance of cabinetry. We really like the AG Series Pulls from Sugatsune. The varied sizes of this hardware make it useable on drawers, cabinets, cubbies, or even closet doors...
The minimal, clean line of this hardware will lend a modern look to your millwork. It will take a little care to install, as the flange is screwed in flush with the surface of the door. So a small niche must be cut out of the door on which this is installed.
Sugatsune, the Japanese hardware manufacturer, is a wonderful source for no-nonsense, functional hardware of all types.
