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.

Please take a moment to view the TB-Various drawing to confirm the output shaft details of the actuator you require, as part numbers and shaft details have changed over the years. Most Part Numbers are still available within 7 – 10 days. Only the most common part numbers are stocked.

The Spec number specifically identifies the actuator and we would provide a replacement built to the same specifications. There may be slight differences with regards to casting finish, leadwire colors, or audible noise level but these differences do not alter the fit, form, or function of the actuator.
