Product Description
LCN 4011 with Friction Latch Arm Metal Cover in Aluminum
The LCN 4011 is the heavy-duty surface closer built for high-traffic commercial doors — school entries, hospital corridors, office building lobbies. It handles the abuse that lighter closers can't, with a cast iron body and full hydraulic control. Ships in Aluminum finish — the standard architectural finish that blends with most commercial door frames.
Pro-Tip from Our Locksmiths: On high-traffic doors that get propped open all day (school entrances, loading docks), spring for the hold-open arm version. It saves the closer mechanism from getting destroyed by wedges and kickstands. The HEDA (Hold Open Extra Duty Arm) is the most popular option for schools.
