Heater A/C Vent Round 2 1 2"

Heater air vent (Part 131364), used on terminal tractors and yard trucks as part of the HVAC (heating & ventilation) system. It’s a 2 ½″ round heater/air vent, meaning it’s the duct or vent through which heated or conditioned air is delivered into the cab interior. This type of vent helps direct airflow from the heater or HVAC system into the operator compartment for comfort and defrost control.
