Find the right vent in three quick steps.
Where it sits, what it does, the size you need — and we'll match you to a cover that fits the opening, not the guesswork.
Where is your vent?
Start with where it sits in your home. That tells us most of what we need.
What does it do?
Not sure? Hold your hand near it while the system runs. Air blowing out is supply; no airflow is return.
Measure the opening, then pick a size.

This is your vent.
Common questions
Measure your duct opening — the hole in the floor or wall — by width and length. That's the size to shop. The faceplate will be larger, but you order by the opening.
Hold your hand near it while the system runs. Air blowing out means supply. No airflow on a larger vent means it's a return drawing air back to the system.
Always the duct opening — not the old cover's faceplate. Covers vary in overhang, so measuring them leads to the wrong size.
