My security door used to close just fine but now it slams. How do I fix it?
The closer contains a lubricant that can thin out in summer, and thicken in winter, so periodically the closer will need an adjustment to either close at a slower rate to avoid slamming, or a faster rate to make sure the door closes fully and can latch. To adjust the door closer, find the small screw in the end of the closer (closest to the door handle) and turn the screw left for slower operation, and right for faster operation. You can see how to do the adjustment in our video to replace the door closer (http://www.ecoadvantage.info/content/care-and-maintenance-tips).
