It does rather get irritating scraping the knuckles. My parents live in a old 1800's cape and there is only about an inch of space between the door jam and knob....and I have big hands. Thinking our ancestors had small hands...-_`Yes! I originally told my architect I wanted ADA thinking that was a 36" door but it turns out a 30" door is ADA, he had to re-draw everything with a 36" door.
