Technical Specifications and Key Features
The Dorma 8616 is equipped with a range of technical specifications and features that make it suitable for heavy-duty commercial applications. Below is a summary of the key technical specifications and features:
- Closer Size: The 8616 supports spring sizes 1 through 6. This range allows for customization based on the weight and size of the door being closed.
- Product Dimensions: The closer measures 13 inches in length, 3.25 inches in width, and 2.125 inches in height. These dimensions make it suitable for surface mounting on a wide range of door frames.
- Door Width Compatibility: The closer is suitable for interior door widths ranging from 2' 4" to 4' 6" and exterior door widths from 2' 6" to 4'. This range ensures that it can accommodate a variety of door sizes commonly used in commercial settings.
- Mounting Type: The 8616 is a surface-mounted closer, which means it is installed on the surface of the door frame rather than being concealed within it. This type of installation allows for easy access and maintenance.
- Material: The closer is constructed from aluminum, which contributes to its lightweight yet durable nature. The use of aluminum also enhances its resistance to corrosion, making it suitable for environments with high humidity or chemical exposure.
- Fasteners: The closer uses sex nuts with a 1-3/8" diameter, which are standard for surface-mounted door hardware.
- Adjustable Features: The closer includes adjustable power, adjustable backcheck intensity, adjustable backcheck positioning, adjustable sweep speed, and adjustable latch speed. These adjustments allow for fine-tuning the closer’s operation to suit the specific requirements of the door and its usage.
- Optional Delayed Closing: An optional delayed closing feature is available, allowing the door to remain open at approximately 70° after reaching its maximum opening angle. This feature is particularly useful in high-traffic areas where doors need to stay open for extended periods.
Installation Considerations
Installing the Dorma 8616 surface-mounted door closer requires careful planning and attention to detail to ensure proper functionality and compliance with building codes. While the provided source data does not include specific installation instructions, several key considerations can be derived from the technical specifications and features of the closer.
- Surface Mounting Requirements: As a surface-mounted closer, the 8616 must be installed on the surface of the door frame. This typically involves securing the closer to the frame using the provided fasteners and ensuring that it is aligned correctly with the door leaf. Proper alignment is essential to ensure that the closer operates smoothly and without resistance.
- Door Hand Direction: The 8616 is a non-handed closer, meaning it can be installed in either left- or right-hand configurations. However, it is important to verify the door’s swing direction and ensure that the closer is installed accordingly to prevent misalignment and operational issues.
- Adjustments for Optimal Performance: After installation, it is necessary to adjust the closer’s power, backcheck intensity, sweep speed, and latch speed to match the door’s weight and usage pattern. These adjustments can significantly impact the closer’s performance and the user experience. For example, a heavier door may require a higher power setting, while a high-traffic area may benefit from a slower sweep speed to ensure controlled closing.
- Optional Delayed Closing: If the optional delayed closing feature is required, it must be configured during installation. This involves setting the closer to remain open at approximately 70° after the door reaches its maximum opening angle. This feature is particularly useful in facilities such as hospitals, schools, and commercial buildings where doors need to stay open for extended periods.
- Corrosion Resistance: Given that the 8616 is designed for use in corrosive environments, it is important to ensure that the installation site is free from excessive moisture, chemicals, or other factors that could degrade the closer over time. Proper sealing and maintenance can help prolong the closer’s lifespan and ensure continued performance.
Compatibility and Application Scenarios
The Dorma 8616 is designed for a wide range of commercial applications, particularly those that require heavy-duty performance and corrosion resistance. Below are some of the key compatibility and application scenarios where the 8616 can be effectively utilized:
