AV components up to 22 lbs per shelf. The angled back corners allow for multiple positioning options, as they can be placed flat against a wall or into a corner of a room, providing ideal viewing angles for a larger area. The lower shelves are perfect for AV components such as digital deceivers, DVRs, Blu-ray, speakers, Apple TVs, or Sonos devices. Installation is kept neat via the built-in cable management with entry and exit points along the length of the column so all power and connectivity wires can easily reach the equipment in an organized, tidy fashion.
