## Questions & Answers

**Q: Does this peephole come with lifetime polished brass ?**
A: Ours was in brushed nickel but it looks like it will last a lifetime.

**Q: can it replace an existing peephole without drilling**
A: It can but you would have to be sure the existing hole is the right size.

**Q: whats best way to drill straight hole that match up on both sides? so it is straight in door & fits gight on both sides?**
A: Watch this video: https://www.youtube.com/watch?v=6pvE27d0Nq0
Summary: determine and mark the exact location of the viewer, drill a pilot hole straight through the door with a small, sharp bit. The easiest way to make it level is a drill with a built in level, but careful eyeballing is good enough.
With the pilot hole drilled, select a bit the exact size of the shaft. If the door is hollow (typical), drill through the outside panel from the outside, stopping well short of the inside panel, then repeat from the inside. This ensures that the remnants of the drilling process from both sides of the door end up inside the door and are neither visible nor obstruct the viewer installation. If the door is solid, drill halfway through from each side. Same process for the same reason. Install the viewer.

It's pretty easy, just make sure you wear eye protection, have sharp bits, and be absolutely certain about the viewer location before drilling. Good luck. This product works awesome in our door.

**Q: Will an external screen door seriously degrade the view?**
A: It could. It depends on how dark the screen is

### ⭐⭐⭐⭐⭐ Looks nice, works fine, easy to install
*by J***L on October 20, 2013*

The product I got was branded as "Stanley," not "National Hardware," but all the same, it does what it says on the box, it's easy to install, it's inexpensive, and it seems solidly built.First of all, functionality. Does it work? I can unequivocally answer "yes" to that one. The optics are of decent quality and if you look from the inside out, you get a good, clear, wide-angle view of the area outside your front door, but if you try to look from the outside in, you see practically nothing at all, eliminating the need for one of those little flip-away covers that people sometimes put in front of peepholes of lesser quality.As for installation: what you don't see in the picture is that the peephole is made of two parts, one threaded on the outside and one on the inside. You have to start by drilling a 1/2" hole in the door. I was a little nervous about this because I knew my door is metal on the outside, but my perfectly ordinary Ryobi handheld drill had no trouble with it. Just be sure not to use a brad-point bit on metal, since it will just damage the brad point; brad-point bits are for wood. Then, you insert the part with the lens from the outside, and the other bit from the inside, and you thread the inside bit over the outside bit. The two little notches are the exact right size for a quarter used by way of a screwdriver, which is probably what you want to do, unless you have a 1/2" screwdriver (do those even exist?).I would like the flange on the inside to be a little larger, the better to cover up any scratches you may make in the surrounding paint, but that's really a minor issue.Given the solid machined metal construction and the decent quality optics, the price seems perfectly reasonable. And did I mention the solid construction? I hadn't expected it, but this thing really does seem to be made of machined brass, and the nickel-plating is strong and thick enough that it didn't chip off anywhere during installation.

### ⭐⭐⭐⭐⭐ Great and cheap.  Here are some tips
*by F***D on June 9, 2013*

For the price, I don't know what more you could ask for. The finish is nice, installation is a breeze, and I was surpised at how wide the field of view is. The only (minor) complaint I have is that the "lip" on the interior part of the peephole could be a little larger to allow for error. As you can see in the picture the lip will only overlap the interior hole by 1/16 of an inch or maybe even less. Here are some tips for installation:-Drill from the inside of the door drilling out.-Before marking the drill hole use blue tape(low adhesion) on the inside of the door to cover several square inches where you plan to drill. To save the finish on the door in case you slip.-Drill a small pilot hole before drilling the main hole.-Use quality, SHARP drill bits.-Dont press too hard while drilling (you wont have to with good bits). If you apply too much force when you drill, as the drill bit pushes through the other side of the door it will either deform the metal or if you have a wood door it could cause large splinters to break off. This is why you should drill from the inside. The other side of the peephole provides much more "cover" over the hole in case you make a mistake. When you notice you're about to drill through the other side, just ease off on the drill and take it nice and easy.The peephole has 2 parts threaded male and female. Just separate the 2 parts, slide in the door from opposite ends of the hole and twist together by hand. Use a large screwdrier to snug it up a bit and your done.

### ⭐⭐⭐⭐⭐ Awesome door viewer!
*by S***U on January 2, 2014*

Great viewing angle and easy to install. I put this about 5 feet up on our front door and I can see the whole porch, our driveway way to the side of the house, and the street! I read other reviews about installation and they are right about the flange sizes, the outside flange is very large and the inside flange is only slightly larger than the half inch hole. Here is how I installed it and it came out perfect with no chips on either side of the door: the hole you need is a half inch so I used a spade bit and a much smaller bit for a pilot hole, maybe 3/16 or so. I marked on the outside of the door first, then drilled straight through with the pilot bit. Then I drilled maybe 1/2" deep with the spade on the inside side of the door out, which is important so you don't get any chips on the hole. Because of the triangle tip at the end of the spade bit it centered itself in the hole. Then I drilled with the spade bit from the outside keeping the drill as level as I could until the two holes met inside the door. The viewer itself has some wiggle room so it should be fine even if the holes are slightly offset from each other. The spade bit also came in handy to tighten the inside part of the viewer as it needs a pretty wide flat-tipped screwdriver, I just used the flat part of the spade bit.Best purchase I have made in a long time!
