How to replace a door closer on a hollow metal door

A door closer is an important component of any hollow metal door, as it ensures that the door closes securely and prevents drafts and noise from entering the building. Over time, however, door closers can wear out or become damaged, leading to a door that no longer closes properly. In this article, we will provide a step-by-step guide on how to replace a door closer on a hollow metal door.

Step 1: Choose the right replacement door closer

Before you can replace a door closer, you need to choose the right replacement for your door. Door closers come in different sizes and weight capacities, so be sure to choose one that is appropriate for your door. You should also consider the type of door closer, such as a hydraulic or pneumatic closer, and choose one that is compatible with your door.

Step 2: Remove the old door closer

To remove the old door closer, start by opening the door and propping it open with a doorstop or wedge. Next, locate the screws that attach the closer to the door and frame. Using a screwdriver, remove these screws and carefully remove the old closer from the door.

Step 3: Prepare the new door closer

Before installing the new door closer, you may need to prepare it by adjusting its settings or mounting brackets. Refer to the manufacturer's instructions for specific details on how to prepare your new closer.

Step 4: Install the new door closer

To install the new door closer, start by positioning it on the door and frame in the same location as the old closer. Use a pencil or marker to mark the location of the screw holes on the door and frame.

Next, attach the mounting brackets for the new closer to the door and frame, using the screws that came with the closer. Be sure to tighten the screws securely, but not so tight that you strip the threads.

Step 5: Adjust the new door closer

Once the new closer is attached to the door and frame, you may need to adjust its settings to ensure that the door closes properly. Follow the manufacturer's instructions to adjust the closing speed, latch speed, and backcheck settings as necessary.

To adjust the closing speed, use a hex key to turn the adjustment screw on the closer. Turning the screw clockwise will increase the closing speed, while turning it counterclockwise will decrease the speed.

To adjust the latch speed, use a screwdriver to turn the adjustment screw on the closer. Turning the screw clockwise will increase the speed at which the latch engages, while turning it counterclockwise will decrease the speed.

To adjust the backcheck setting, use a hex key to turn the adjustment screw on the closer. Turning the screw clockwise will increase the resistance to the door opening beyond 90 degrees, while turning it counterclockwise will decrease the resistance.

Step 6: Test the new door closer

Once the new closer is installed and adjusted, test the door to ensure that it closes smoothly and securely. Open the door and release it to see if it closes on its own. If the door closes too slowly or too quickly, you may need to adjust the closer settings again.

In conclusion, replacing a door closer on a hollow metal door is a relatively simple task that can be accomplished with a few basic tools and some careful attention to detail. By following the steps outlined in this article, you can choose the right replacement door closer, remove the old closer, install the new closer, and adjust its settings to ensure that your door closes properly. Remember to always wear safety goggles and gloves when working with tools, and consult a professional if you are unsure about any aspect of the replacement process.
