Product Description
LCN 4011-FL Door Closer with Fusible Link Arm, Left Hand, Aluminum (689)
The LCN 4011-FL is LCN's heavy-duty cast-iron 4010 Series closer with a fusible link arm, mounted parallel arm on the push side of the door. The arm holds the door open in normal use; when the link melts at 165F it lets go and the closer shuts the door. A common spec for corridor and stairwell doors in schools, hospitals and other high-traffic buildings. Full hydraulic control with adjustable spring power, plastic cover, Aluminum (689) painted finish.
Pro-Tip from Our Locksmiths: A fusible link arm is handed, so match the arm to the door: this one is Left Hand. The link is a one-time part. Once it melts, replace it before the hold-open will work again. Check with the local fire marshal before you put any hold-open on a rated door.
