Steel Supply Curved Grilles, Spiral Registers Direct to Duct - IERA (EVAR)
Double deflection steel grid for air injection with individually adjustable straight fins, vertical to the front and horizontal in the rear. The grid face is curved to adjust to the diameter of the duct. Includes fasteners for installing, back deflector scoop, and seal on the frame to prevent air leaks.
The standard color is Metallic Gray but we can also do them in White or Matte Black as a custom order (~3 week lead time)
*Our EVAR curved grilles have an allowance of plus/minus 2 inches on the diameter of the duct. Example: an EVAR curved grille that is stated to fit on a 16" duct can also fit on a 14" duct or an 18" duct. In rare stockout cases, we may fulfill your order with a size that is within 2" of your requested duct size
