Automatic Door Closer Double Spring 15 Years of use 150lb Load Capacity Door Closers for Home Door use,2 Pack

You probably can install this new closer on your exiting brackets in which case installation could take as little as 2 minutes. Regarding the included part that connects to the door frame, your installation might need a bracket that attaches to the front AND side of the door frame which is a different bracket than is included in this item. Search Amazon for FLORIDA JAMB BRACKET. Don’t throw away any of the hardware from your existing closer until the new closer is installed in case you need some parts from the old closer. I’d suggest taking a pic of your existing closer before removing so that you can easily see which way the brackets should be oriented during the installation.When I installed this new closer it worked perfectly without the need to adjust closing speed. The only minor issue that I had with this item is that it is difficult to remove the parts from the packaging. Use scissors.
