Door Latch Pullback Kit, Motor Driven, 22 to 28 Volt DC, Includes 8’ Power Lead, Screw, Motor Mount, ACME Link Assembly, Hex Wrench, For Corbin Russwin/Yale Exit Device

The MLRK1-COR is a practical and cost-effective way to convert a mechanical Corbin Russwin’s ED4000, ED5000 or Yale 7000 series device to an electrified latch pullback device. The retrofit kit will maintain all UL listings on the device and for peace of mind is backed by CAT’s 3-year no hassle warranty.

The MLRK1-COR is a high quality, cost-effective method of converting a Corbin Russwin 4/5000
& Yale 7000 series device to an electrified latch pullback exit device. Since our kit retracts the push
pad, the device can be electrically dogged allowing the device to remain in a push/pull state, for as
long as is desired. Patent Pending Push to Start (PTS)Technology allows for an easy post-installation
adjustment of the latch/latches. Last but not least, it features our motor module with 2 different torque
settings from energy-conscious to high torque to get the tough jobs done!
