How Do I Identify My Actuator Motor?

Your actuator motor can be easily identified by a SPEC number, which is stamped directly in the housing by the shaft extension. This number typically begins with a UL designation (i.e. UL6 or UL14) followed by a four or five digit number. This number is required before we can assist you with your replacement needs.
