The APB and APBS Series adjustable depth wall brackets provide flexible solutions for mounting 19 inch rack equipment in telecom and IT environments. Constructed from durable 14 gauge steel and supporting up to 100 lb, these brackets deliver reliable support for patch panels, switches, and other rack-mounted devices. With adjustable depth from 12 inch to 18 inch, both series accommodate varying equipment sizes without requiring disassembly. The APBS Series adds an integrated 12 inch accessory shelf for supporting non-rack equipment, allowing mixed-device installations without the need for a full cabinet. Together, these solutions support efficient installation, organized cable management, and adaptable deployment in space-constrained environments.
