How to Adjust a Standard Door Closer in 6 Steps

Your door plays a crucial role in creating the first impression for anyone entering your space. However, a misbehaving door can be a nuisance, whether it's slamming shut too quickly or moving at a snail's pace. Fear not! Adjusting your door closer can be a straightforward task with the right tools and a little guidance.

Understanding Your Door Closer

 Before diving into the adjustment process, it's essential to grasp the basics of a door closer. These devices, whether mechanical (hydraulic) or electromagnetic, are attached to the top of the door to regulate its movement. On standard closers, three hydraulic valves collaborate to ensure a smooth door operation:

  • Backcheck: Prevents the door from opening too fast and slamming into walls or objects.
  • Sweep (Main Speed): Regulates the movement of the door until it's a few inches away from latching.
  • Latching Speed: Controls the closing speed in the final inches before latching.

Six Simple Steps to Door Closer Harmony

 Step 1: Remove the Cover

If adjustment valves are not visible, remove the cover. Loosen fasteners and slide it off or, if tension-held, simply pull it off to reveal the adjustment valves.

Step 2: Close all Valves

Turn all three hydraulic valves clockwise until they stop, ensuring they are fully closed.

Step 3: Adjust the Backcheck

Make 1.25-1.5 turns counterclockwise on the backcheck valve. Open the door to ensure it comes to a steady, controlled stop, preventing slamming or catching from wind.

Step 4: Adjust the Sweep/Main Speed

Make 1.5-2 turns counterclockwise on the sweep valve to adjust the closing speed. Clockwise turns slow down the closing speed.

Step 5: Adjust the Latching Speed

Make 1.5-2 turns counterclockwise on the latching speed valve. The correct latch speed depends on the door's location (e.g., increase for outside doors, decrease for office doors).

Step 6: Test the Door

Open and close the door several times to test adjustments. Make small tweaks as needed. Remember, even a tiny adjustment can make a significant difference. Clockwise decreases speed; counterclockwise increases it.
