Chatsworth 44U, 2 Post Seismic Rack, Square-Punched Painted Rails, Black (13856-703) - 19"W x 7'H

The Chatsworth Standard 2-Post Seismic Rack is specifically to support network equipment in areas with seismic activity. When earthquakes occur, equipment racks move back-and-forth with the building causing violent vibration through racks and equipment. An earthquake can easily damage or destroy non-seismic racks and equipment that are not carefully braced. The welded, steel Seismic Frame Two-Post Rack resists the swaying motion caused by earthquakes to reduce the amount of vibration transferred through the rack to equipment and is less likely to be damaged during a seismic event, which means faster network recovery.

The Seismic Frame Two-Post Rack supports 19" EIA-310-D compliant or 23" wide equipment with two pairs of mounting rails that can be spaced 6" (150 mm) or 3" (80 mm) apart. The mounting rails are marked and numbered with RMU spaces and can be attached so that numbering starts at the bottom or top of the rack mount space. Choose threaded or square-punched mounting rails with a painted or zinc plated finish. The mounting holes in threaded mounting rails are tapped with #12-24 threads to speed installation of panel-mount equipment with #12-24 screws. The square-punched rails accept cage nut hardware allowing you to change threads at each RMU to match equipment mounting requirements.

CPI's Seismic Frame Two-Post Rack ships fully assembled and includes a Two Mounting Hole Ground Terminal Block for bonding the rack to the Telecommunications Grounding Busbar and 50 each equipment mounting screws or cage nuts and screws. The rack is rated for a 1,000 lb (453.6 kg) seismic Zone 4 load per Section 4.4 of the Telcordia Technologies, Inc. GR-63-CORE Network Equipment Building Systems(NEBS) requirements.
