Mounting Hardware Installation 

 

Note! Due To High Torque Applied During Installation, Re-Use Of Motor 
Mounting Hardware Is Not Recommended. All Hardware Components Should 
Be Replaced Whenever A Motor Is Removed. 

Depending on motor type, either 3/4” or 1” bolts are used for securing the motor(s) to the screen 
frame. Refer to table below for hardware sizes for each motor. When installing the bolts, note that 
the 3/4” motor bolts are installed from the underside of the screen frame (Figure 1), while the 1” 
bolts are installed from the top of the motor. Both configurations require hardened washers under 
the bolt heads as well as under the Flex-Loc nuts.
