The MLRK1-YAL6 is a practical and cost-effective way to convert a mechanical Yale 6000 series device to a motorized latch retraction device, while maintaining the listing. Our easy-to-install motor-driven kit installs in minutes and includes an optional built-in request to exit. 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 YAL6 features an updated MM module, energy conscious while still being capable of getting tough jobs done.
