Question:
How do I install the MXA910W-A in a drop ceiling?
Answer:

The MXA910W-A easily fits ceiling grids that use the 9/16 inch T-Bar size and have an opening of 23-7/16” by 23-7/16“ or larger.

Ceiling grids that use the 15/16 inch T-Bar are a tight fit and the installer may need to remove the surrounding ceiling tiles to have more flexibility on the grid and be able to press the mic into the desired position. In some cases, the installer may need to press a few of the surrounding ceiling tiles up above the grid to create flexibility in the grid to more easily press the mic into the desired position.

The following chart shows a few popular drop ceiling brands, and the expected installation procedure for each.
