Middle Atlantic Products has announced equipment mounting solutions rated for seismic and mission-critical applications. Seismic-certified product categories now include two-post racks, server racks, security racks, cable management racks and slide-out racks. The company's unique riser bases that support racks in raised-floor applications now also offer increased weight load ratings. Middle Atlantic has also completed testing and seismic-certification for new racks such as the R2-44S 19" Relay Rack and its existing MK and WMRK racks. Further testing has led to increased seismic weight ratings for the MRK, VRK, VMRK and MRK-AXS enclosures.
