nVent Hoffman FMB1000 This connection bar mechanically connects a system actuator with the secondary door interlocking kit, and allows the secondary door to be opened only when the master door is opened first.Feature: zinc plated connection bar for interlocking combinable floor standing enclosure doorsAdvantage: the interlocking bar mechanically connects the system actuator FMA, of the primary door, to the interlock kit FMS, of the secondary door; as the bar is already cut to size customers can easily mount it to the other components of the interlocking systemBenefit: the primary door is fully dependant upon the enclosure's primary door when mounted along with the system actuator FMA and the secondary door interlock kit FMSa this means that the secondary door may only be opened by first opening the primary doorComment: to build an enclosure system that consists of multiple doors each with an integrated interlocking system then each neighbouring primary and secondary door will require an interlocking system to be mountedThe interlocking system consists of: system actuator FMA, interlocking bar FMB and a secondary door interlock kit FMS
