#1 | Q: do the short length louvers move to adjust the air flow direction to the right or left? If not, do you have a 4x10 with a damper that only discharges to the left or right? A: The front short louvers are fixed, not adjustable, since these are floor grilles. The 210 series is adjustable but its not meant for floor use. https://www.hvacquick.com/products/brands/TRUaire Asked on 2019-10-19 by Elliott |

#2 | Q: The floor opening is 5 x 11. Do you have that size? A: We could do that size in the Dayus custom line, but the Truaire is only available in the listed sizes. They are undercut by a 1/2 inch, but that doesnt seem to be enough for your application. Asked on 2014-11-20 by Bob FL |
#3 | Q: can I get a quote for a 14x20 floor grille with a 2flang on the outside instead of the 1 flang ? A: These are available only in the configurations listed. Asked on 2013-06-21 by mark |
