LCN 4010 Heavy Duty Door Closer, Aluminum Powder Coat Finished, Cast Iron, Right-Handed, Regular Arm

The LCN 4010 door closer has a right-handed, double lever arm, an aluminum powder coated finish, and is for use in heavy duty applications on interior or exterior doors. The hydraulic cylinder is made of cast iron, has a forged steel piston and double heat treated steel pinion for resistance to wear, and is certified for 10 million cycles. All-weather hydraulic fluid helps reduce the need for seasonal adjustment. The double lever arm can be installed for a regular . The door closer is right-handed for installation on doors with hinges on the right side, and includes a plastic cylinder cover. The spring force required to open the door is adjustable from sizes 1 to 6 for interior doors up to 60" wide, or exterior doors up to 48" wide, to help comply with the Americans with Disabilities Act (ADA) when properly installed. The aluminum powder coat finish helps provide resistance to corrosion. The door closer meets American National Standards Institute (ANSI)/Builders Hardware Manufacturers Association (BHMA) A156.4 grade 1 standards for commercial buildings. It is also Underwriters Laboratories (UL) listed for a 3-hour fire rating, and complies with the UL 10C positive pressure fire test.

A hydraulic cylinder attached to an arm regulates the speed of closure with separate adjustments for the door's sweep and latch (the final 10 degrees) phases of movement, and backcheck for opening resistance to protect walls and guard against wind gusts. Single lever (also called track) arms maintain a low profile when installed on either side of a door, while double lever arms provide greater mechanical efficiency. In either a regular (on the hinge, or pull, side of the door) or a top jamb (on the reverse, or push side), the double lever arm projects perpendicular to the door. A parallel arm must be installed on the push side, for the double lever arm to occupy the recess of the door frame when at rest for a low profile. LCN manufactures door closers and other door hardware products. The company, founded in 1926, is headquartered in Princeton, IL.
