Stratus White Plastic 2'x2' CONE Air Diffusers
The diffusers came quickly and look fantastic. They are in the dining area of my sub shop. A much better option than trying to make the old metal ones look good again! I’ll be ordering more of these diffusers for additional locations.
Perfect fit in 2x2 ceiling grid. I mounted inline duct fan directly to it to exhaust heat from my server room. Actually added two (exhaust and input) but the input side needed a $5 collar as well. Note: My goal was only to supplement the airflow from the existing wall mounted ac unit (this won't cool the server room all by itself) and replace the ceiling tiles we removed for ventilation. Otherwise it was super simple and looks great (much better than the pictured prototype I made from a plastic tote!)
Sales promptly answered my email question. I placed my order on-line immediately and delivery was within two days. Product worked great in my application.
Plastic is the only way to go. Great product, easy to install.
