Automatic Arms have an electric motor to retract the tarp back into the housing. The arms automatically deploy the tarp using spring tension within the arm pivot. This entire process is done by simply turning a switch. Automatic Arms are great for any application up to 40'. Tarping peaked loads is made easy because the arms lift the tarp up and over the load.
