Description
The new MLRK1-CAL77 is a practical and cost-effective way to convert a mechanical Cal-Royal 77 or PD26
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. It easily secures onto the backactivating bracket and is secured with (2) screws, in a matter of seconds. The only hole you’ll need to drill
is for the wire raceway. PTS allows for a smooth post-installation adjustment of the latch/latches. Last but
not least, it features an updated MM4S module with 3 different energy consumption settings from energy
conscious to high torque to get the tough jobs done! The only hole you’ll need to drill is the raceway! It
utilizes our PTS “Push to Set” technology making post-installation adjustments incredibly easy.
