Convert your hinged door into a self-closing one with the Prime-Line KC10HD Safety Spring Door Closer. Installation is a breeze thanks to the closer and plastic slide plate being surface mounted. Use this spring door closer on doors and it can close up to 150 pounds of force. It can also be used on both left and right-handed doors. The door closers feature an adjustable closing force and speed. Constructed of diecast materials with a white painted finish, this safety spring door closer can complement any style door. They are U.L. listed with a 1/2 hour fire rating and have a 1 inch wide base, 4-1/4 inch hole center spacing and 4-3/4 inch arm. These closers operate in a pushing-closed manner, rather than in a pulling-closed method, and they do not have a hold open feature. The closer arm of this safety spring closer has the ability to swing a full 180 degrees, but once it is mounted in place, the door’s distance of swing will be reduced to the point of where it makes contact with the bullet-shaped housing of the closer. All fasteners and installation instructions are included with this item. Be sure to view the manufacturer’s How-To Installation Video also linked to this page.
From the Manufacturer
These safety spring-activated door closers are constructed of diecast materials and come in a white painted finish. They are U.L. listed with a 1/2 hour fire rating, and can be used to close doors weighing up to 150 lbs. These closers feature an adjustable closing speed and they are non-handed, allowing them to be used on both left and right-handed swinging doors. Both the closer and the plastic slide plate are surface-mounted, and are easy to install. These closers operate in a pushing-closed manner, rather than in a pulling-closed method, and they do not have a hold open feature. Distance of travel: The closer arm of this safety spring closer has the ability to swing a full 180 degrees, but once it is mounted in place, the door’s distance of swing will be reduced to the point of where it makes contact with the bullet-shaped housing of the closer. For a rust and weather resistant closure, consider model numbers KC50HD (white) and KC57US (brown) which are suitable for outdoor/exterior use, designed for use with lightweight gates and screen doors. All fasteners and installation instructions are included with this item. Other colors/finishes include: black, brown, chrome plated and satin chrome plated. Be sure to view the manufacturer’s How-To Installation Video also linked to this page, in the upper left hand corner. Application of white lithium grease to internal compressing springs may be desired, but you should avoid using lubricants like WD-40 which breaks down lubricating grease.

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.

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 bought it for my basement staircase door. I'm glad with its performance.Pros:White color goes very nicely with my white doorSmaller size than most door closers; it does look bad at allVery well constructed, no plastic parts in the main mechanismVery reasonable price compare to other closersVery easy to install; fits very well on the door jamComes with nice long screwsCons:Closes door a little hard; I installed rubber in the door frame to absorb the slamThe main housing will prevent the door to open all the way (180 degrees)The strong spring might make some noise; I would apply some machine oilOverall, this a very effective product for a very reasonable price. I will definitely buy it again, if needed.

So the Prime Line KC10HD Door Close is a great design, easy to install and adjust, and it worked perfectly with my application. My issue is with Amazon...and I guess the manufacturers packaging process. So mine was missing 1 of the tiny white vanity plugs. I reached out to Amazon for a plug, which is unavailable and was offered a $3 refund, a fair exchange for a one cent plug, but not what I wanted. I wanted what I paid for and suggested a swap which was acceptable to my Amazon chat partner Juvy. The issue was I either had to take my return to a Whole Foods 14 miles away or pay for a UPS return as my package value didn't qualify. What??? How did their problem become my problem? In the end I accepted a $5 refund and my Door Close is missing 1 vanity plug. Oh, and I am a monthly paying Amazon Prime member. Poor customer service amazon.

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.

We got this in lieu of a pet door so that the cat could come and go from the bedroom. We have it close just softly enough that it doesn't click shut. Love that the tension could be adjusted in this way. Solid purchase, honestly.

Basement door was constantly left open and taking direct hits from the garage entrance door. The Prime-Line closer was easy to install (I watched the short video) and closes the door fully after each use. No more colliding doors.

I bought this product 2nd time and had the same issue as my 1st purchase. After few weeks, it start making noise when door opens/close. Last time I was able to replace it with a new one and it is working fine for me for 8-10 months without issue.But this time I did not get enough window to return it back and now I have to suffer this product.
