Damper Box = Air Deflector
Hardware jargon gives me a headache. It’s tough explaining to customers that need a register cover that we call them floor registers. They are also called vent covers, heat registers and “stupid thing for that dumb hole in my floor that’s making the room chilly.” Only the last one is the official term.
“Damper box” is another confusing term. The damper box, also called an air deflector (or “open-shut thingamadoo”), is the part of the floor register that actually fits into the floor. It has louvers that open and close the same way venetian blinds do. If the louvers are open then air can flow out of the vent and through the floor register. If the louvers are closed then the floor register blocks all the air in the vent from entering the room. The register is “dampening” the flow of air into the room and so the louvers are called a “damper box.”
If you don’t need a damper box then you’ll want to buy a return air grille (”skinny register”).
