Horizontal (wxh) |
Horizontal (WxH) For a wall return application, be sure to order the aluminum return air grille width by height. (Ex: If the aluminum return grille opening size is 20" wide by 14" tall, order 20x14. If the grille opening size is 14" wide x 20" tall, order 14x20). If it is for a ceiling return application, you may order either direction or specify your preference. |
