Abstract: A fire extinguisher mounting unit includes a cabinet, a frame and an access panel. The cabinet and frame are formed from a flame retardant, high impact plastic with the access panel being formed of a grooved acrylic sheet. The cabinet and frame have cooperating portions which properly position the access panel within the unit, which unit may be mounted either in a recessed position whereby the unit, with the exception of the frame, is recessed into a support, or in a surface position whereby the rear wall of the cabinet is mounted on a support.
