Why is BGR the #1 AV Enclosure? The BGR is designed to hold 20% more weight but be lighter than its predecessors. It offers more space efficiency for equipment mounting and cable management with Lever Lock™. It has options designed for system future proofing without disturbing the existing system. BGR is designed for today and tomorrow's AV applications and with multiple form factors it supports multi-rack systems, single rack systems or a mobile systems. The 23" width gives you extra room in "no-man's land" for front-to-back cable management and for mounting small devices on Lever Lock™ freeing up valuable rackspace.
