Surface Mounted Door Closer Basics
A surface mounted door closer is a mechanical device installed on the surface of a door or frame to control its closing and opening motions. These closers use hydraulic or pneumatic mechanisms, often combined with springs, to regulate door movement and ensure it closes securely after being opened. They are highly versatile, suitable for various door materials such as aluminum, metal, and wood, and can be installed in multiple configurations, including regular arm, parallel arm, and top jamb setups. Surface mounted closers are popular due to their ease of installation and cost-effectiveness compared to concealed alternatives. They are commonly used in commercial spaces like schools, offices, and healthcare facilities to enhance security, reduce energy costs by preventing drafts, and comply with fire safety standards. Despite being visible, these closers offer adjustable features such as dual valve speed control for closing and latching speeds, making them reliable and adaptable for different environments.
Surface vs Concealed Comparison
Surface and concealed door closers each offer distinct advantages for different applications:
- Surface closers are visible when installed, typically mounted on the door or frame. They are easier to install and adjust, making them cost-effective for commercial spaces. These closers are highly durable and suitable for high-traffic areas, with options for various arm configurations.
- Concealed closers are hidden within the door or frame, providing a cleaner aesthetic appearance. They are ideal for spaces prioritizing design, such as luxury apartments or high-end commercial buildings. Concealed closers offer improved vandal resistance and can be suitable for both in-swinging and out-swinging doors.
While surface mounted door closers are more common due to their versatility and ease of maintenance, concealed closers are gaining popularity in design-conscious environments where aesthetics are paramount. The choice between the two often depends on factors such as door type, usage frequency, and architectural requirements.
Adjusting Surface Door Closers
To adjust a surface mounted door closer, follow these steps:
- Remove the cover from the closer body to access the adjustment screws. Some of the screws are on the front; others are on the top.
- Locate the numbered or lettered screws that control different functions:
- Screw 1 or “C” adjusts the main closing speed
- Screw 2 or “L” controls the latching speed
- Some models have a “BC” screw for backcheck adjustment
- Use a flathead screwdriver or Allen key to make small turn adjustments.
- Turn screws clockwise to slow down movement, counterclockwise to speed up.
- Test the door after each adjustment and fine-tune as needed.
For optimal performance, adjust the backcheck to slow the door at about 75 degrees when opening, set the main closing speed for smooth motion, and fine-tune the latch speed to ensure proper closing without slamming. Remember that door closer speed may vary slightly with temperature changes, so seasonal adjustments may be necessary.
Mounting Style Options
Surface mounted door closers offer several mounting styles to accommodate different door configurations and architectural requirements. The main mounting options include:
- Regular Arm Mount: The closer body is installed on the door’s pull side, with the arm attached to the frame. This is the most power-efficient option but may be less aesthetically pleasing.
- Parallel Arm Mount: The closer is mounted on the door’s push side, with the arm folding parallel to the door when closed. This style is preferred for improved aesthetics and allows for built-in door stops.
- Top Jamb Mount: Used when the door has a narrow top rail, the closer body is mounted on the frame’s push side with the arm attached to the door face. This option is suitable for doors with limited space.
- Track Arm Mount: A sleeker alternative featuring a sliding track instead of a scissor arm, often used in offices or areas where aesthetics and accessibility are important.
- Corner Bracket Mount: Less common, this style is used for doors with angled or arched top rails, with the closer mounted on a bracket in the frame’s corner.
Each mounting style has specific applications and benefits, allowing for versatile installation options to suit various door types and architectural designs.
Dual Valve Speed Control
Surface mounted door closers typically feature dual valve speed control, allowing for precise adjustment of the door’s closing action. This system utilizes two separate valves to control different phases of the door’s closing motion:
- Closing speed valve: Regulates the main swing speed from fully open to about 10 degrees.
- Latching speed valve: Controls the final 15 degrees of closing, ensuring proper latching.
This dual valve configuration enables fine-tuning of the door’s closing behavior, accommodating various door weights and environmental conditions. Some advanced models may also include additional valves for backcheck control or delayed action, further enhancing their versatility and performance in different applications
