ABSTRACT:
Described are seismic-resistant equipment cabinets and door latches for enabling a hinged door to remain attached to the cabinet during a seismic event of a particular intensity. The door has a latch disposed along one edge of the door. The latch includes a latch-keeper receptacle and a latching bolt disposed in the latch-keeper receptacle. The latching bolt is slideable between a latched and an unlatched position. The frame has a latch keeper assembly attached to an edge thereof. The latch keeper assembly is positioned to enter the latch-keeper receptacle when the door latches to the frame. The latch keeper assembly includes a protruding member having a tapered edge and a latching-bolt aperture to receive the latching bolt when in the latched position. The tapered edge establishes a close fit by the latch keeper assembly within the latch receptacle to limit relative motion therebetween during a seismic event.
