Using the Lowell BP - 300 grille is easy. First, decide on whether you want a horizontal or vertical installation for the recessed setup. Then, place your 8 - inch speaker and 12 - inch analog clock into the respective cutouts on the 18 - gauge steel panel. Attach the detachable round bezel grille for a finished look. Remember, you'll need to provide your own clock, speaker, and backbox. When it comes to maintenance, a simple wipe with a dry cloth can keep the white finish looking great. Avoid using abrasive cleaners as they may damage the steel. Also, make sure the installation area is dry to prevent rusting. And since it's made in the U.S.A. with certified U.S. steel, you can trust its quality for long - term use.
