Door Closer Frequently Asked Questions
What is a hydraulic door closer?
A hydraulic door closer is a mechanical device installed on doors (typically interior/exterior swing doors) to control the door’s movement—specifically, to automatically close the door smoothly and gently after it is opened, while preventing slamming, excessive speed, or sudden impacts. It relies on hydraulic fluid (oil) to regulate motion, making its operation far more controlled and quiet compared to spring-only door closers.
Can a hydraulic door closer be installed on any type of door?
No, a hydraulic door closer cannot be installed on every type of door. Its compatibility depends on several critical factors, including the door’s physical properties, intended use, and environmental conditions. Installing an incompatible closer will lead to poor performance (e.g., failure to close, door damage, or safety hazards) and may violate building codes.
What is the backcheck on a door closer?
Backcheck (often written as one word: backcheck) on a door closer is a hydraulic safety feature that slows down a door when it is opened too quickly or forcefully, typically in the final 15–20° of its swing (usually activating between 70° and 90° of opening).
Core Purpose of door closer backcheck
- Prevents damage: Stops the door from slamming into walls, furniture, or glass.
- Protects hardware: Reduces stress on hinges, frames, and the closer itself.
- Improves safety: Prevents injuries from sudden, violent door swings (e.g., from wind or rough use).
