Rated 3 out of 5 by 1reviewer.
Rated 3 out of 5 by Product was not exactly what I expected. When I talked with Grainger Technical, I told them I was looking for a return grill to put in a suspended ceiling. Above the suspended ceiling was the return air that went back to a rooftop HVAC unit. I wanted a return grill that I could put an air filter in it.This return grill had a small filter in it already. It would not accept a standard air filter without modifications. Also, the grill did not fit in the suspended ceiling tight enough. It wanted to fall out. I needed to drill holes in the diffuser so I could wire it up to the ceiling joists. I installed 3 units in different locations. What should have been a quick job to lay in these return grills in the suspended ceiling took way too long. March 24, 2013
