Yes, this is installed on our front door on the inside. No problems.
My purchase was about 5 inches, sorry.
Standard hinge pin size
These leave no marks on my white doors
I have the door to my bathroom set to about 70-75 degrees to keep the door from hitting the tub. I definitely think it could be set to near 90 degrees. In my situation i would have trouble enterig the room if i set it any further.
The bottom between the door stop and hinge to reduce friction and wear.
Will not work on doors with larger hinge pins. Have Jeld-Wen French doors and this is to small
The satin nickel hinge pin resists corrosion (rust) however, if the finish wears off then the metal underneath may be subject to corrosion. Thus far, I haven't had any problems with it rusting.
