Square D EZ Meter-Pak meter centers provide reliable, versatile, and compact multi metering equipment for multi unit residential and commercial construction. The main devices are available as main circuit breakers, main fusible switches, or main lug terminal boxes, and residential and commercial branches are available in ring or ringless type. EZ Meter-Pak meter centers have accessories and spare parts for field replacements and design flexibility. This part is a special mounting channel for installing EZM metering equipment. The channel measures 72 inches and can be cut to length as needed. Mounting holes must be drilled on site to accommodate the installation requirements. An EZM72MC can be used in place of the standard channels with the EZM enclosure.
