Great product and easy to install. It only took the right size bit to drill through the door. My closest bit on hand was a 5/8", but the hole should be closer to 9/16" It still looks great and it still works great.

4.0 out of 5 stars Make sure you have a 9/16 bit 1st
Reviewed in the United States on April 6, 2015
Verified Purchase
Fair warning 9/16 is not a common bit. I ended up having to buy a 5 piece drill bit set from harbor Freight after neither lowes or Home depot carried the right bit. Since this was going on our front steel door i didn't want to use a spade bit or try a 1/2 bit and get try and force it in. However once i bought the right tool for the job the knocker installed in seconds and looks/sounds great.

Pro tip. Use a pilot hole all the way through then using the 9/16 just go half way on either side. Otherwise you'll end up with a nasty looking "bullet hole" vs a clean neat circle.

5.0 out of 5 stars Great Value. Easy to Install if you are replacing an old identical knocker.

I purchased this for the doors on our condo building to replace the original knockers, which were heavily oxidized. Great value and easy to install. I purchased it because it had the exact same measurements as the original knockers with the screw and peephole the same distance apart. That made it easy to simply remove the old one and install the new one. I would up replacing over 30 knockers in our building. I am hoping the brushed nickel finish will hold up better to the elements than the brass-finish version. I installed these almost a year ago, and so far, so good.

It looks great, but it feels cheap. The lens fell apart in the box and I thought I broke it. The knocker connection has to sit a certain way for it to actually work, but it moves around too much and gets stuck.
