This is an improved version of Aero's Easy Cover tarp systems, featuring the Aero Easy Cover 14 gauge Galvanized Round Steel 107.5" Rear Cross Arm. It replaces the old teardrop cross arm design and is now compatible with the Round Cross Arm Claw Kit, allowing you to securely fasten your tarp to the dump bed. Please note that this updated circular steel cross arm is different from the previous Aero Legacy Teardrop Cross Arm.
