Commercial door closers play a vital role in maintaining the security and accessibility of your business premises. Properly adjusted door closers ensure that doors close smoothly and securely, preventing drafts and unauthorized entry. However, over time, door closers may require adjustment to maintain their functionality. In this guide, we’ll walk you through the steps to adjust a commercial door closer, helping you ensure safety, convenience, and efficient operation.
Materials You’ll Need:
Before you start adjusting the door closer, gather the following materials and tools:
- Screwdriver (Phillips-head and flat-head): For making adjustments and tightening screws.
- Hex wrench or Allen key: Necessary for some door closer models.
- Lubricant (e.g., silicone-based spray): For lubricating moving parts.
- Measuring tape: Useful for taking precise measurements.
Steps:
Determine the Type of Door Closer:
Commercial door closers come in different types, including surface-mounted and concealed models. Surface-mounted closers are visible on the door’s exterior, while concealed closers are hidden within the door frame or door itself. Knowing the type of closer you have will help you locate and access the adjustment controls.
Locate the Adjustment Valves:
Depending on the brand and model of your commercial door closer, you may find one or more adjustment valves. These valves control various aspects of the door closer’s operation, including closing speed, latching speed, and backcheck (resistance to being forcibly opened). Commonly, these valves are labeled and located on the door closer body or arm.
Adjust the Closing Speed:
To adjust the closing speed, follow these steps:
Locate the valve labeled “closing speed” or similar.
Turn the valve clockwise to increase the closing speed or counterclockwise to decrease it. Start with small adjustments and test the door’s closing action after each adjustment.
Adjust the Latching Speed:
To adjust the latching speed, if available, follow these steps:
Locate the valve labeled “latching speed” or similar.
Similar to the closing speed adjustment, turn the valve clockwise to increase the latching speed or counterclockwise to decrease it. Again, make gradual adjustments and test the door’s behavior.
Adjust the Backcheck (if applicable):
Backcheck controls the resistance the door closer offers when someone tries to force the door open. To adjust the backcheck, follow these steps:
Locate the valve labeled “backcheck” or similar.
Turn the valve clockwise to increase backcheck resistance or counterclockwise to decrease it. Test the door’s behavior to ensure it provides the desired level of resistance.
Lubricate Moving Parts:
Apply a silicone-based lubricant to the moving parts of the door closer, including the arm and pivot points. This ensures smooth operation and prolongs the door closer’s lifespan.
Test the Door:
After making adjustments and lubricating the door closer, test the door’s operation. Open and close it several times to verify that it closes smoothly and securely without slamming or remaining ajar.
Make Further Adjustments (if necessary):
If the door closer still doesn’t function as desired, repeat the adjustment process, fine-tuning the settings until you achieve the desired closing and latching speeds.
Conclusion
Properly adjusting a commercial door closer is essential to maintain the safety and convenience of your business premises. By following these steps and making necessary adjustments, you can ensure that your commercial door functions efficiently, closes securely, and provides a welcoming and secure entrance for your customers and employees.
