- Connect the Arm⁚ Connect the arm to both the door closer body and the header bracket. Ensure the arm is properly adjusted for optimal closing performance. A parallel arm bracket will likely be required to facilitate this mounting style.
Both top jamb and parallel arm mounting offer viable alternatives to standard mounting, providing flexibility to accommodate various installation scenarios. Always consult the manufacturer’s instructions for specific guidance and safety precautions.
Adjusting Speed and Latch Settings
Once the door closer is installed, fine-tuning the speed and latch settings is crucial for ensuring smooth and controlled door operation. These adjustments prevent the door from slamming shut or failing to latch properly. Most door closers feature two or more adjustment valves, typically controlling the closing speed and latching speed. Understanding how these valves work is key to achieving optimal performance.
Understanding Adjustment Valves
Door closers typically have at least two adjustment valves⁚ one for the main closing speed and another for the latching speed. Some models may also include a backcheck adjustment, which controls the resistance when the door is opened wide.
- Closing Speed Valve⁚ This valve regulates the speed at which the door closes for the majority of its travel. Turning the valve clockwise typically reduces the closing speed, while turning it counterclockwise increases the speed. The goal is to set a speed that allows the door to close smoothly without slamming.
- Latching Speed Valve⁚ This valve controls the speed at which the door closes during the final few inches of its travel, ensuring it latches securely. A slightly faster latching speed is usually desirable to overcome any resistance from the door seal or latch mechanism. Turning the valve clockwise reduces the latching speed, and counterclockwise increases it.
- Backcheck Valve (if equipped)⁚ This valve provides resistance when the door is opened beyond a certain point, preventing it from swinging open too forcefully and damaging the door, frame, or surrounding objects. Adjusting this valve can help protect against wind gusts or accidental forceful opening.
Step-by-Step Adjustment Process

- Adjust the Closing Speed⁚ Start by adjusting the closing speed valve. Turn it slightly clockwise to slow the door down or counterclockwise to speed it up. Observe the door’s movement and adjust until it closes smoothly without slamming.
- Adjust the Latching Speed⁚ Next, adjust the latching speed valve. Turn it slightly clockwise to slow the latching speed or counterclockwise to increase it. Ensure the door latches securely without bouncing back open.
- Test the Door’s Operation⁚ Open and close the door several times to test the adjusted settings. Pay attention to the closing speed, latching action, and overall smoothness of operation.
- Fine-Tune as Needed⁚ If necessary, make further small adjustments to the valves until you achieve the desired performance. It may take some experimentation to find the optimal settings.
- Consider Environmental Factors⁚ Remember that temperature changes can affect the door closer’s performance. Colder temperatures may cause the door to close more slowly, while warmer temperatures may increase the closing speed. You may need to make seasonal adjustments to compensate for these changes.
By carefully adjusting the speed and latch settings, you can ensure that your door closer provides reliable and controlled door operation, enhancing safety and security.
