Martin Pierce launched his Ergo as his first contemporary door hardware design. These custom steel door handles and cabinet knobs have smooth ergonomic contours to fit your hand. Our Ergo door hardware series is available in 304 stainless steel and in bronze. In May 2012 we introduced the latest additon to the Ergo series which is door handle that is both ADA compliant and one that meets California and Federal fire safety standards. We have also begun to cast more of this line in silicon bronze with a softer oil rubbed patina finish.
