Easy install, I enlarged the existing peep hole to accommodate the new one. Rather than drilling new holes in the door I used permanent Acrylic mounting tape where the holes would have been drilled and tightened the new peep hole. It’s solid and has a good sound.
I had been searching for a replacement door knocker to fit the existing holes in my front door for some time. I found just what I needed here. The shipping was prompt. Unfortunately, I found a scratch on the face of the knocker when I opened it. I contacted myknobs and submitted the requested photo of the piece. I was contacted shortly after that by both email and phone and was shipped a new one within a day or two. Fantastic experience in this era of indifferent or no follow up at all. I highly recommend them.
