A Vent TabTM is a replacement part for the A/C and Heating vent control knob/clip which controls the air flow direction inside your vehicle. The original plastic clips are prone to failure and before our product was invented, the only way to replace it was to replace the entire vent assembly, which ranges from $150-$500. Our patent pending, VenttabsTM design slides into place with no dis-assembly of the vent required. Once installed it performs just like the original . Save time and lots of money with Vent TabsTM .
