Lcn 4010 Heavy Duty Door Closer, Aluminum Powder Coat Finished, Cast Iron, Left-Handed, Hold Open Arm, 4011 H 689 TBSRT LH

Size:Aluminum Powder Coat/Hold-open Style:Left Handed The LCN 4010 door closer has a left-handed, double lever, hold-open 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 , and the arm's hold-open feature will hold the door in an open position when engaged. The door closer is left-handed for installation on doors with hinges on the left 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. Specifications Cylinder Cast iron with forged steel piston and double heat treated steel pinion Arm construction Forged steel main arm, stamped steel forearm Cover Plastic ing Hinge (pull) side Interior door width 24" to 60" Exterior door width 24" to 48" Maximum door opening 140 degrees ANSI/BHMA grade Grade 1 Cycles 10 million UL compliance 3-hour fire rating Commercial grade door closers mechanically return a door to closure for security, conservation of heating and cooling, and fire safety. 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.
