Abstract: A cabinet structure for storing a fire extinguisher including an open front box-shaped housing and a cover mountable thereon. Mating recesses in the top wall of the housing and hinge tabs in the top side of the cover cooperate to provide pivotal engagement between the cover and housing and mating flange members on the housing and cover facilitate padlocking of the cover in mounted disposition on the housing. The hinge tabs are breakable in response to the application of a pulling force on a grip formed in the top side of the cover to facilitate emergency access to the cabinet. A peripheral lip and interior tabs on the cover facilitate proper centering of the cover on the housing.
