The LCN 4110 Series represents a line of heavy-duty door closers designed for high-traffic installations. These closers are specifically engineered for push-side parallel arm mounting applications. The series, along with the 4010 and 4020 series, meets stringent industry standards, including UL and cUL listing, and ANSI/BHMA Grade 1 certification. They are characterized by a cast iron construction, a 1-1/2” diameter piston, and a 30-year warranty, emphasizing quality and durability. The LCN Green Dial spring power indicator simplifies adjustment, and optional finishes and primers are available for specific environmental conditions.
Series Overview and Applications
The LCN 4110 Series is part of a broader family of heavy-duty door closers – the 4000 Series – manufactured by Allegion. These closers are intended for demanding environments where frequent door operation is expected. The 4110 Series distinguishes itself through its mounting configuration: push-side parallel arm. This mounting style is suitable for applications where a traditional top jamb or hinge-side mounting is not feasible or desirable. The series is designed to meet the requirements of both interior and exterior doors, with sizing options available to accommodate varying door widths.
The documentation highlights that the 4010 Series mounts hinge pull side, the 4020 Series mounts push side top jamb, and the 4110 Series mounts push side parallel arm. Detailed mounting instructions are available in the respective catalog pages for each series.
Body Construction and Materials
The core of the LCN 4110 Series is a robust body construction. The cylinder is made of cast iron and incorporates a full-complement bearing, contributing to smooth and reliable operation. A key component is the 1-1/2” diameter piston, which facilitates controlled door closing. The design also includes a double heat-treated steel pinion journal, enhancing the overall strength and longevity of the closer.
These materials and construction techniques are intended to withstand the rigors of frequent use and provide long-term performance. The use of all-weather fluid further contributes to the durability of the closer, protecting internal components from environmental factors.
Quality and Durability Features
Several features contribute to the quality and durability of the LCN 4110 Series. The use of all-weather fluid ensures consistent performance across a range of temperatures and humidity levels. The LCN patented Green Dial spring power indicator is a notable feature, simplifying the adjustment process by visually indicating the spring power setting. This eliminates guesswork and allows for precise control over closing speed and force.
Furthermore, the series is backed by a 30-year warranty, demonstrating the manufacturer’s confidence in the product’s reliability. Optional features, such as an SRI primer, are available for installations in corrosive environments, providing additional protection against degradation.
Installation Considerations
Installation of the LCN 4110 Series requires attention to specific details. The closer is application-specific handed, meaning that the correct handedness must be selected based on the door’s swing direction. A standard plastic cover is included, with optional handed metal covers available for enhanced aesthetics and durability. Plated finishes are also available for the cover, arm, and fasteners.
The 4110 Series is available with adjustable spring sizes ranging from 1 to 5, or 6 only. Cylinder sizing is also a factor, with sized cylinders suitable for interior doors up to 5’0” and exterior doors up to 4’0”. Non-sized cylinders offer adjustability for interior doors up to 4’6” and exterior doors up to 3’6”. Proper sizing is crucial for optimal performance and compliance with accessibility standards.
The documentation confirms that the LCN 4110 Series meets ADA requirements, ensuring accessibility for individuals with disabilities. It is also UL and cUL listed for use with self-closing doors, including those equipped with regular or fusible link arms. Testing and certification under ANSI/BHMA A156.4 Grade 1 further validate the product’s quality and performance.
Finish Options and Accessories
The LCN 4110 Series offers a range of finish options to suit various aesthetic preferences and environmental conditions. A standard plastic cover is included, but optional handed metal covers are available for a more refined appearance. Plated finishes can be applied to the metal cover, arm, and fasteners, providing enhanced corrosion resistance and visual appeal.
For installations in corrosive environments, an optional SRI primer is available. This primer is specifically designed for use with powder coat finishes, providing an additional layer of protection against degradation. Powder coat finishes are offered in standard colors, as well as a large selection of custom colors, allowing for seamless integration with building décor.
Compliance and Certifications
The LCN 4110 Series adheres to several important industry standards and certifications. It meets ADA requirements, ensuring accessibility for all users. The closer is UL and cUL listed for self-closing doors, verifying its safety and performance. Furthermore, it has been tested and certified under ANSI/BHMA A156.4 Grade 1, the highest standard for door closers, indicating exceptional quality and durability. These certifications provide assurance that the LCN 4110 Series meets rigorous performance and safety criteria.
Conclusion
The LCN 4110 Series door closer is a heavy-duty solution designed for high-traffic applications requiring push-side parallel arm mounting. Its robust construction, featuring a cast iron cylinder and 1-1/2” diameter piston, combined with features like the Green Dial spring power indicator and a 30-year warranty, ensures long-term reliability and ease of use. Compliance with ADA requirements and certifications from UL, cUL, and ANSI/BHMA A156.4 Grade 1 further solidify its position as a high-quality, dependable door closing solution.
