Build cleaner, more serviceable AV infrastructure with the Middle Atlantic ERK-3525-AV. This 35 U, 25 in deep floor-standing rack is designed for standalone deployments where equipment density, airflow, and long-term stability all matter. Its fully welded construction gives the enclosure the rigidity needed for permanent installations, while the vented top and vented side panels help support thermal management in enclosed technical spaces. The ERK series is also built for real-world integration work. Convenient lacing points and slotted rail brackets make cable routing more orderly, reducing strain on terminations and helping technicians maintain a professional finish during initial buildout and future service. For projects that require partitioned multi-bay layouts, the rack can be ganged to support thermal control and security strategies across adjacent enclosures. When the installation demands more than a commodity frame, the ERK-3525-AV delivers the structural confidence and practical details that justify its place in a serious AV room. It is also seismically certified when installed with ERK-Z4 brackets, adding another layer of assurance for environments where equipment protection cannot be left to chance. With a lifetime warranty, RoHS compliance, and GREENGUARD certification, it is specified for infrastructure that is expected to stay in service.
