Using the Lowell BME87 blind - mount enclosure is easy. First, make sure you're installing it from beneath a drywall or plaster ceiling as it's designed for situations where above - ceiling access isn't available. The mounting and installation aids like knockouts, U - clips, and torsion receptacles will help you secure the enclosure. You can choose a screw - mount or torsion grille type according to your preference. When it comes to maintenance, since it's made of heavy - gauge steel, it's quite durable. But you should check the foam pad for acoustical treatment regularly for any signs of wear and tear. Also, keep it clean by wiping it with a dry cloth. If you notice any damage to the steel structure, it's best to contact a professional for repair. Remember, this product is made in the U.S.A. with certified U.S. steel, so you can trust its quality.
