Move multiple linear actuators in synchronous using Firgelli's FA-SYNC-X 

The Firgelli Automation Synchronous Control Board allows you to move multiple Feedback actuators in step with the same speed irrespective of load. Unsynchronized actuators can lead to bending loads which is likely to be disastrous for both the load and the actuator.
The FA-SYNC-2 will allow you to move two actuators in sync and the FA-SYNC-4 will allow movement of four actuators.
Common applications include, but are not limited to: wine cellar trapdoors, RV roof lifts, tonneau covers, and table lifts.
