The MLRK1-VD is a practical and cost-effective way to convert a mechanical Von Duprin series device to a motorized latch retraction device, while maintaining the listing. Our easy-to-install motor-driven kit installs in moments and includes a built-in request to exit (US ONLY). It is equipped with push-to-set (PTS) technology allowing for an easy post-installation adjustment of the latch/latches. Last but not least, the VD features an updated MM5 module, energy conscious while still being capable of getting tough jobs done.
