Using the Lowell BP - 700 grille is easy. First, decide on the horizontal or vertical orientation for your surface - mount installation. You can then place your 8 - inch paging speaker in the appropriate cutout and your 12 - inch analog clock in the other one. Remember, the clock, speaker, and backbox are not part of the package, so you'll need to provide those. When handling the grille, be careful as the 18 - gauge steel panel can be sharp at the edges. To keep it looking good, clean it regularly with a soft, dry cloth. Avoid using abrasive cleaners as they may damage the white finish. Since it's made in the U.S.A. from certified U.S. steel, you can be confident in its quality and durability for long - term use.
