LCN automatic operators are the proven standard in schools and health care facilities for over 20 years. They are easily retrofitted into existing doors and frames, as well as new construction. LCN low energy electro-hydraulic and pneumatic automatic operators feature a heavy duty closer with a slow opening function.

The 4640 was designed primarily for manual opening applications that occasionally require automatic opening.
