## 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.

## 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.
