To use this mobile device holder, first mount the back plate on the wall using the provided stainless - steel sheet metal screws. Then attach the front plate with the cradle to the back plate using the threaded posts. Install the front hook and secure it with the set screws. Place your laptop or other devices in the holder, and the rubber bands will keep them in place. When it comes to maintenance, simply wipe the holder with a soft, dry cloth regularly. Avoid using abrasive cleaners as they may damage the matte black finish. Make sure to check the screws periodically to ensure they are tight and the holder remains secure.
