Automatic Arms 

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.

Double Wrap Teardrop Technology 

All Automatic Arm sets come standard with Pulltarps Double Wrap Teardrop Technology. A process where the Hem Tube slides into the Universal Teardrop Pullbar and the tarp wraps around the bar twice in order to eliminate bunching and the stress on the stitching. The Urethane Bumpers are then fastened to the pullbar. This keeps the tarp centered and reduces noise.
