The Corbin Russwin DC6210 is a high-performance door closer designed for commercial applications that demand durability, compliance, and adjustability. As part of the DC6000 Series, it is a Grade 1, ADA-compliant device that supports parallel arm mounting and is suited for heavy use environments such as schools, office buildings, healthcare facilities, and retail complexes. This article provides a detailed overview of the DC6210’s features, installation process, and adjustment procedures, based solely on the information provided in the source documentation.
Overview of the Corbin Russwin DC6210
The DC6210 is a parallel arm mounting door closer that allows for installation on the interior side of an out-swinging door using an offset angle bracket. This design enables the arm to face outward, making it ideal for applications where space or aesthetics are considerations. The door closer is manufactured by Corbin Russwin, a subsidiary of Assa Abloy, and is part of the broader DC6000 Series. It is UL/ULC/UL10C listed, meeting fire and cycle requirements, and is also ANSI A156.4 compliant.
The device is constructed with a cast iron core and features a silver aluminum coating. It is available in an aluminum finish (designated as DC6210-689) and is designed for both interior and exterior use. The closer supports adjustable spring sizes ranging from 1 to 6, allowing it to accommodate a wide range of door weights and opening dynamics. The DC6210 is also equipped with features such as backcheck intensity and location valves, which provide additional control over door movement.
Installation Process
The installation of the Corbin Russwin DC6210 requires careful adherence to the manufacturer’s specifications and the use of appropriate hardware. The following steps summarize the key procedures involved in mounting and configuring the door closer, based on the source material.
Step 1: Preparation and Bracket Installation
Before mounting the door closer, the door and frame must be inspected for compatibility. The DC6210 requires a minimum 3-inch top jamb for proper installation. The offset angle bracket is a critical component for parallel arm mounting and must be securely fastened using four self-drilling screws. These screws are included in the package and are designed to penetrate the door material without the need for pre-drilling.
To ensure proper alignment, the self-drilling screws should be marked on the drill bit to confirm that sufficient material is removed to allow for full insertion. Once the bracket is in place, it is secured using the included hardware. The offset bracket allows the door closer to be mounted on the interior side of an out-swinging door while directing the arm outward.
Step 2: Mounting the Closer Body
After the offset bracket is installed, the door closer body is mounted onto the bracket using two 1/4-20 x 1/2” oval head machine screws (OHMS). These screws are included and are used to secure the closer body in place. The next step involves rotating the spindle 45 degrees using a crescent wrench. This preloads the closer and prepares it for the attachment of the main arm.
The main arm is then attached to the upper spindle end. This arm connects to the door and is responsible for transmitting the closing force. Once the arm is in place, the arm rod is mounted onto the offset angle bracket. This rod connects the arm to the door closer body and must be adjusted to ensure optimal performance.
Step 3: Final Adjustments and Testing
The final step in the installation process involves attaching a 5/16” hex head screw with a washer to the top of the spindle. This secures the main arm onto the closer. The arm loop is then slid onto the arm rod and adjusted to the desired position. A 7/16” hex head screw and washer are used to set the overall length of the arm loop and rod.
For maximum closing force, the connection between the main arm and the arm loop should be positioned approximately three inches from the face of the door. For normal operation, the arm loop and rod can be adjusted to be parallel with the face of the door.
Once all components are in place, the door should be opened and allowed to close several times to test the operation. The DC6210 is factory-set to a size three configuration, which is suitable for most standard applications. However, adjustments can be made if necessary.
Adjusting the Corbin Russwin DC6210
The DC6210 features two primary adjustment valves: the closing (sweep) valve and the latching valve. These valves allow for fine-tuning of the door’s closing speed and behavior.
Closing Valve
The closing valve controls the speed at which the door closes from the fully open position to approximately 20 degrees. In the example provided, the closing speed was set to six to seven seconds. Adjustments are made by turning the valve clockwise to slow the speed or counterclockwise to increase it. This valve is particularly important in environments where a controlled and gradual closure is necessary, such as in schools or healthcare facilities.
Latching Valve
The latching valve governs the speed at which the door closes and latches. In the installation example, the latching speed was adjusted to two to three seconds. Turning the latching valve clockwise slows the latching speed, while turning it counterclockwise increases it. Proper adjustment of this valve ensures that the door latches securely and efficiently, which is critical for security and compliance with building codes.
Additional Adjustments
The DC6210 also includes backcheck intensity and location valves, which allow for further customization of the door’s closing behavior. These valves help prevent the door from slamming and provide a controlled stop at the fully open position. However, it is important to note that the backcheck feature should never be used in place of a door stop. Over time, using the backcheck as a door stop can lead to loose mounting screws and potential malfunction of the closer.
Compatibility and Specifications
The Corbin Russwin DC6210 is designed to meet a wide range of commercial and regulatory requirements. It is ADA compliant, meaning it is suitable for use in facilities that must accommodate individuals with disabilities. The closer also conforms to UL and UL10C standards for fire door applications, making it appropriate for use in high-volatility environments.
The device is constructed using durable materials and is available in a painted or plated finish. It is compatible with a variety of door types, including hollow metal doors, and is designed for both interior and exterior use. The DC6210 supports multiple mounting configurations, including standard regular arm, top jamb, and parallel arm mounting.
Available Arm Configurations
The DC6210 offers several arm options to suit different installation needs:
- Standard Arm: A non-hold open regular arm with a parallel arm mounting bracket.
- Hold Open Arm (A1): Combines a regular hold-open arm with a parallel arm mounting bracket.
- Heavy-Duty Parallel Arm (A2): A heavy-duty parallel arm with hold open functionality.
These options allow installers to select the most appropriate configuration based on the door’s size, weight, and usage pattern. The parallel arm mounting bracket is particularly useful in applications where the door is out-swinging and requires an internal installation.
Maintenance and Warranty
Proper maintenance is essential for the long-term performance of the Corbin Russwin DC6210. After installation, the date of installation should be marked on the body of the door closer using a permanent marker. This allows for easy reference in the event of future maintenance or warranty claims. If the closer malfunctions, the installation date can help determine whether the unit is still under warranty.
The DC6210 is available with security screws for high-vandalism applications, providing an additional layer of protection against tampering or theft. These screws are designed to resist unauthorized removal and are recommended for use in public spaces or high-traffic areas.
