To adjust a storm door cylinder, which typically controls the door's closing speed, you need to locate and turn the adjustment screw found on the end of the cylinder. Turning this screw alters the flow of air or fluid within the cylinder, thereby changing how quickly the door closes.
Locating the Adjustment Screw
Most storm door closer cylinders have a single adjustment screw located at one end. This screw is usually small and may require a Phillips or flathead screwdriver.
Adjusting the Closing Speed
The primary reason to adjust a storm door cylinder is to control its closing speed. A door that slams shut needs to be slowed down, while one that closes too slowly might need to be sped up slightly.
Here's how to make the adjustment, based on common practice and the provided reference:
- Identify the Cylinder: Find the hydraulic or pneumatic cylinder attached between the door frame and the storm door. Most doors have one or two cylinders. The main adjustment is usually on the primary closing cylinder.
- Find the Adjustment Screw: Look for the screw located specifically on the end of the cylinder.
- Make the Adjustment: According to the reference, you should "take the screw that's on the end of the cylinder. And just give it a slight turn maybe a quarter to a half turn. In a clockwise direction tighten."
- Turning the screw clockwise (tightening) typically slows down the door's closing speed by restricting the flow inside the cylinder.
- Turning the screw counter-clockwise (loosening) typically speeds up the door's closing speed by increasing the flow.
- Test the Door: After making a small turn (like the suggested quarter to half turn), test the door's closing speed. Open the door fully and let it close naturally.
- Fine-Tune: If the speed isn't right, make another small adjustment (again, a quarter turn or less) and test again. Repeat this process until the door closes smoothly at the desired speed without slamming.
Important Considerations:
- Small Adjustments: Always make small turns to the adjustment screw. Even a slight turn can significantly change the speed.
- Don't Overtighten: Do not force the screw or tighten it excessively, as this can damage the cylinder.
- Multiple Cylinders: If your door has two cylinders, one often controls the main closing speed, and the other might control the latching speed at the very end of the closing cycle. Adjustments are usually made on the main cylinder first.
- Latching Speed: Some cylinders have a second adjustment screw specifically for the final few inches of closing (latching speed). If present, this screw controls how quickly the door pulls closed just before it latches.
- Door Weight and Usage: Heavier doors or doors subject to wind may require different settings.
Adjusting the cylinder allows you to ensure your storm door closes safely and effectively, protecting your home from the elements and preventing wear and tear on the door and frame.
