Remotely seal ducted HVAC systems for duct leakage testing without climbing up and down ladders. Simply attach the Pole RAT to any standard painter's pole and use it to both attach and place the Vent Caps as needed. When snapped to the top of the Vent Caps, the Pole RAT holds down the spring-loaded fastener so there's no tension on the cord. Raise to the vent, torque as necessary, and press gently to push the foam gasket against the surface. Simply roll the Pole RAT to the side and the button pops out.
