PDQ OWNERS FORUM

These air conditioning vents are available on zoro.com. Model 3840RWH grille with damper. Zoro # 0707.1400.

I had never heard of Zoro before, but they shipped the next day. When ordering, Zoro sent me a discount code for my first order. Cost worked out to about $10 each, including shipping.

As a follow up to these - I decided to remove the dampers for better airflow. Conveniently, the dampers on most of them fell out on their own, so don't get these if you want dampering !
