## Description

Product Description 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.

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.

Review: Keeps the Office Scent Free - My office is ~25' away from two restrooms in the company. I hear everything, and the odor eventually wafts to my door as well. I've asked the two primary culprits to simply close the door and leave the fan running, but that requires too much effort apparently. I've closed my own door, but it always seems that someone will need to see me, or they visit and use my office as a safe refuge until the fog lifts. This week I installed two of these simple door closers, and the problem has been solved. Sure, somebody could somehow wedge the door open, but we've already discovered that closing the door is too hard for them to accomplish, so finding something to keep the door open is way beyond their capabilities. The product was easy to install, each one took less than 10 minutes to install. I mounted them on steel door frames, so I had to first drill 1/8" pilot holes. If you are installing on a wooden door frame you'll need a smaller pilot hole. The one drawback as other reviews pointed out is the slight noise the spring makes as it is compressed and released. The sound is not bad, but it caught everyone's attention when they opened the door. Everyone stopped, looked around, moved the door some more, and tried to discover the source of the new noise, but they could not see the device from the hallway. The commercial doors in the office a quite heavy, but this device has not trouble closing them. I adjusted the closer to close the door a bit slowly and gently, but the amount of force used is adjustable. The price is perfect! I'll never get reimbursed for mounting and installing these in the office, so my payback will be the joy of not having my office smell like poop, or even worse, poop sprayed with Lysol..... Gag!

## Questions & Answers

**Q: After installation, is there an easy method or control, excluding the use of a separate door stop, to keep the door wide open if needed?**
A: There is not an "easy" method to hold the door open. The only thing to do is use a doorstop.

**Q: Can the closer be disabled without uninstalling it?  It appears from the picture that maybe the closing rod could be removed and re-inserted?**
A: As best that I remember, the closing rod can be removed from the hole in the spring assembly.  did in fact uninstall the unit by pulling the rod out and separating the door from the spring. The problem was that the spring required so much rotational torque to fully close the door that I needed to use the next to last hole on the cylinder and the cylinder kept on snapping back to a position where the last hole couldn't be reached. I finally managed it by jamming the cylinder by placing the screwdriver in a adjacent hole. This allowed me to hold the cylinder still so that I could reposition the rod .

**Q: I know this is a door closer, but it does soft close or does it accelerate to close?**
A: I have it set to just reach the closed position but not to overcome the door latch and lock the door. In this case it is a soft close. If you increase the tension to close the door until it latches, it will probably accelerate somewhat due to the momentum gained while it swings shut.

**Q: How much pressure does it take to open? Will my 90 lb. Lab. be able to push it open?**
A: You can adjust the closing (and thus opening) force. It should be no problem to adjust it such that a dog can push open the door.

### ⭐⭐⭐⭐ Very functional and well-made with some limitations
*by D***S on August 18, 2015*

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.
