Prime-Line KC10HD Safety Spring Door Closer – Easy to Install to Convert Hinged Doors to Self-Closing – Diecast Construction, 4-1/4 In. White, Non-Handed (Single Pack)

The installment of this spring door closer is incredibly simple. Adjusting the tension is simple enough, and most importantly, it works! I needed this for a door that opens outward onto the patio, and because of this wasn't so sure it was going to function as well, as if it had been installed on a more traditional door. The poor weather has hindered the installation until now and we couldn't be more impressed with this! When I say there was nothing to the installation, I really mean it! We really like the smaller, more attractive appearance of this spring door closer in comparison to others. I will admit that it does make a creaking sound as the spring tightens when opening the door, but it's hardly a nuisance. I was so afraid one of the kids were eventually going to break the glass on the door as it swung open an hit the outdoor light you can see in the picture. Also on windy days the door practically pulls right out of your hands and does the same thing. I'm not sure why the previous owners hadn't done anything to rectify this issue when they installed the doors to begin with. This is the perfect solution in our case, and we can't be happier. Now, I just hope it will be alright outdoors! This is an inexpensive option and is well worth it.

The photo shows that the Prime-Line Astra KC10HD Safety Spring Door Closer can be mounted on the door case molding (which isn't flat) using the four screws that come with the product. FYI, it is straddling a concave portion of the molding. When the tension was adjusted strong enough to fully close the door the mechanism sort of growls when you open and close the door, I think because the springs are wound up so tightly the surfaces are rubbing together. However, when enough tension was applied it did shut the door very smoothly until it actually latched. Also, I found that I had to use an Allen wrench to hold the output disk in place so I could screw in the arm in the correct hole. The short threaded rod they give you doesn't help much in some cases where it won't fit between the closer and the adjacent wall. All in all I'm very happy with the product. About drilling the holes: When drilling the holes, it helps if you first use a drill that just barley fits inside the four through-hole mounting hole locations in the closer to mark one location and create a "center" point for the smaller bit that will be used for the screw pilot holes. Hold the mechanism in the place you want to mount it and then insert this larger drill bit into one of the top mounting holes. Only drill a slight divot in the surface of the molding to create a center for the smaller bit you'll use next. Don't drill all the way through the molding with this larger bit or you'll screw up big time! Now remove that first larger bit from the drill, blow out the saw dust, and insert a drill with the inner screw shank diameter through the mechanism so the actual pilot hole for the screw can be drilled all the way through the molding with the mechanism in place, that way it will be at the correct angle. I think the bit I used for this was about 3/32 inch. Don't make the screw pilot bit too small or you'll crack your molding when you install the screws. Once this is done, you can install one of the top mounting bolts and tighten the closer up against the molding. Now you can finish drilling the other three larger holes with very little hassle to help guide the smaller pilot drill bit when you drill the remaining three pilot holes.

I bought this spring door closer for a side kitchen door to keep our indoor cat from getting out. The door is old and the frame is warped so the door naturally swings completely open to a stationary position. Before I found this closer on Amazon I didn't even know this kind of closer version existed. I was planning on buying one of those bulky hydraulic rod closers from a big box home improvement store. This one is nice because it only takes a few screws, it is on the opposite side of the door so you really don't see it. It also can be installed in cramped spaces since the mechanism doesn't take up very much space. They offer various colors so you can match it to your décor, and it looks easily paintable. It is made in China, but feels sturdily made. It only took me about ten minutes to install it on a wood door. I didn't even drill any pilot holes first, the screws included were perfect for wood. The biggest drawback is the tensioning of this device. I'd recommend two people if you have to really ratchet up the tension on the spring. They include a tensioning screw which you use to wind it up. Once you go around 3 holes or so, it gets quite dangerous if you lose control of the tension and I can see the spring whipping around and possibly pinching your fingers. We have a fairly heavy vintage warped wood kitchen door working against gravity and it took about 3 holes worth of tension which might have been at the limit of what you can safely wind this to. The instructions clearly say to not over-tension the spring or it will buckle, but there is no clear description of what the limit is. The closer had some minor spring "groaning" when opening and closing the door. I added a little machine oil to see if it quiets down after breaking it in. Overall I'm happy with the purchase. It is well-priced, easy to install, and a very simple design. Once it is configured for your setup you should be good for a long time.

I think it works really well. Especially for the price I just bought my 4th one. One of them make a noise. Since I read some people complain about it. Watch your fingers when putting tension to it but once it’s installed your golden

Es discreto, funciona bien la diferencia con los brazos es que este azota la puerta. Al poco tiempo comenzó a rechinar pero con un poco de wd40 se le quitó y hasta el momento sigue funcionando perfecto. Se puede ajustar la tensión (fuerza) para el cierre de la puerta.

The main body of this product works fine as does the connection arm the main issue with it though is the extremely cheap wood screws that they give you. The heads of two of the screws completely stripped off the bodies after installing it into wood, very cheap material used if you have your own screws I would recommend using them or making sure you drill good pilot holes. The instructions don't specify this very well.

Does what I bought it to do.. that is 5 stars in my books. Easy install too

This door closer appears to be somewhat coarse. The paintwork in the screw holes were coming off even though it was new (see picture). The threads for the closing arms also had some paint stripped off. As the closer is of metal construction paint may, depending on the finishing process used, come off quite easily. It was easy enough to fasten, but I was missing one plastic plug for the retaining screws (see picture) Finally, this closer is very noisy. When closing or opening the door, it emits a loud creaking noise. Measured with my phone, the noise levels in the room rose from 40+dB to 60+dB. (video attached). If you are looking to close a door inside your home, I would give this a miss. The common overhead door closer (while more expensive and more involved to install) is much quieter. However for applications where noise is not an issue, this closer works as described and is quite easy to install. There appears to be no fine adjustments to the closing rate. You can only select to put the closing arm into the available holes. Amendment - May 2021 Some time after posting the above review, I found some other reviewers who dismantled the unit and added lithium grease to the spring inside. Did this and after some time the closing noise is nearly inaudible.
