The VRK-HR is an innovative accessory that allows an integrator to mount full width rack products vertically inside an Atlas Sound WMA12-19-HR or WMA16-19-HR half width wall rack. This accessory easily mounts into either rack unit and creates 5RU of mounting space for full size components. When installed in the WMA12-19-HR, the vertical components occupy the entire rack, and when installed in the WMA16-19-HR, 4RU of half width space is still available in the rack. The VRK-HR enables an integrator to use a half width rack in even more installations as its flexibility allows multiple configurations for multiple types of equipment.
