Question: If I get this with a satin nickle finish and then have it engraved, will the engraving show through in brass?
Document: Great Door knocker. It has a very clean look to it and the peep hole isn't obvious. It's a little on the thin side but I guess you don't need much. It was easy to get engraved. It wasn't the easiest to install. Would have liked a template to assist with lining up the screws. Other than that, it looks very professional.
this is something I have been looking for and couldn't find in the box stores so it came in good time and the only draw back is a template to drill the mounting hole which it doesn't have but good material and finish.
Pros: Adds a distinctive look to the front door, with the addition of a viewer. It looks great with the new lock set and door bell.Cons: Viewer is extremely poor quality.Even with the poor viewer I would buy it again, although I know I need to get a usable viewer.
This is a great looking door knocker. I tried to find one with a viewer in satin nickel at Lowe's, Home Depot, etc. with no success. This is a good size and very simple to install. We have had it eight months and it looks as good as the day it came out of the package. Highly recommended!

Also, start with small pilot holes at first so you don't damage the door's finish beyond the drilling area. Next, this comes with two sets of mounting screws: one set for thinner doors, and one set for thicker doors. Neither worked for me.
So, overall I am very happy with this purchase. With this knocker/viewer, a little bit of paint, and a new entry mat, my entry way looks brand new.
My door knocker with viewer has been installed with no problems.It is exactly what I wanted. Looks very nice on my textured fiberglass stained entry door.Joan Sheppard
I like the overall door knocker, but the lens in the peephole was broken, thus causing me to have to purchase a replacement peep hole. Quality assurance has something to be desired.
We wanted to replace the knocker on our new house because the old one was gold, and I am not a fan of gold accent pieces. Unfortunately, the old knocker's viewer hole was slightly larger (and not drilled straight) than this one, so it took a little more time than we had wanted to spend to put it on.
Answer: yes
