If you have a heavy-duty door or want to install a self-closing door, a spring hinge may be the best option for you. But heavy-duty hinges are not easy to find and expensive to replace. If you’re looking for an economical solution, you can purchase an add-on spring hinge door closer. This door accessory can be installed on one hinge. The installation process is very simple – simply remove the old hinge, slip the spring over the pin and install. Then, test it to make sure it works properly. The longer pin is available for three 1/2”-inch-hinge doors.
Spring hinges are made of two interconnected springs that act together to adjust the force of the closing door. These springs are located at either end of the door and are usually positioned in the center of the door. A good spring hinge will make it difficult to open the door, but it will prevent the door from opening and closing too quickly. Typically, double-lip hinges are made of two ball bearings and a pincushion.
