Featuring diecast construction and a clean white finish, it offers adjustable tension for customizable closing force. UL-listed with a ½ hour fire rating, it ensures safety and durability. Easy to install with included hardware, this closer converts hinged doors into self-closing ones, ideal for both left and right-handed doors. ## Description Convert your hinged door into a self-closing one with the Prime-Line KC 10HD 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 up to 150 pounds. 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 ½ 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. Review: Not a Soft Close Door Closer - I bought this door closer expecting a smooth, soft-closing action, but it was very disappointing. Despite adjusting it, the door closes too abruptly and doesn't provide the soft close I was looking for. The spring mechanism feels harsh, making it noisy and unpleasant to use. If you're specifically after a soft-closing door closer, I would not recommend this product. It may work as a basic self-closing mechanism, but it certainly doesn't deliver a smooth or gentle closing experience.

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. ## Customer Reviews ### ⭐ Not a Soft Close Door Closer *by P***H on 24 July 2026* I bought this door closer expecting a smooth, soft-closing action, but it was very disappointing.

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. ## Frequently Bought Together - Prime-Line KC10HD Safety Spring Door Closer – Easy to Install to Convert Hinged Doors to Self-Closing – Diecast Construction, 4-1/4 In.
