LCN LCN

LCN is a manufacturer of concealed and surface mounted door closers. In addition to traditional closers, LCN also produces automatic operators and fire/life safety and high security models.

Automatic operators are easily retrofitted into existing doors and frames, as well as new construction. LCN low energy electrohydraulic and pneumatic automatic operators feature a heavy duty closer with a slow opening function. LCN’s electromechanical automatic operators utilizes a motor gearbox and control box to perform the opening and closing function.

LCN Sentronic® closer/holders are designed to hold swinging doors open in normal use and release to automatically close the doors under fire conditions.

High security closers feature a vandal-resistant design for correctional, institutional and other high traffic applications. Special components minimize tampering and vandalism.
