Abstract
In the electronic equipment shelter disclosed herein, protection of electronic equipment from both normal and abnormal environmental conditions, including severe electromagnetic pulses, is provided by employing a construction in which panels having inner and outer aluminum skins are joined together in an assembly employing extruded box tubes at each edge with the outer skins being welded to each other and to the tubes so that a complete conductive envelope is obtained. The necessary door opening is made electromagnetically unitary with the main shelter body by metal spring finger gaskets which are compressed by means of a multiplicity of linked dogging assemblies all around the door frame.
