About the LR100MDK

The LR100 Series electric latch retraction kit adds electric access control and dogging functionality to compatible mechanical exit devices. When energized, its motor retracts the latch and depresses the pushpad, allowing momentary or sustained push-and-pull operation of the door.

Designed for field installation and retrofit applications, this kit supports a 36-inch opening and is compatible with M9900 devices.
