A lighting fixture assembly includes a housing assembly that forms an interior. A valve mechanism is associated with the housing assembly and is configured to automatically vent fluid from the interior to the atmosphere when the pressure in the interior exceeds a threshold level. Otherwise, the valve mechanism seals the interior from the atmosphere. The lighting fixture also includes a pressure-equalization mechanism, separate from the valve mechanism, which is also associated with the housing assembly. The pressure-equalization mechanism is configured to, upon activation, substantially equalize the interior pressure with the atmosphere pressure and to otherwise seal the interior from the atmosphere.

A locking mechanism for securing such enclosures as vending machines is disclosed. A hasp is mounted on the interior of the enclosure and a mounting bracket having a flange and a lock hole is disposed on the exterior of the enclosure. To securely lock the enclosure, a hasp key is passed through an opening in the enclosure proximate the mounting bracket. One end of the hasp key includes an engagement mechanism that engages a hasp key aperture through the hasp. On the other end of the hasp key is a lock hole which is generally aligned with the lock hole on the exterior of the enclosure when the hasp key is engaged. A lock may then be disposed through the lock holes, limiting a would-be intruder's options to gain access to the inside of the enclosure. A sliding T-handle lock cover is also described. The sliding T-handle lock cover includes a flange and slides over a T-handle lock and aligns with a flange of a cover plate. When the flanges of the T-handle lock cover and the cover plate are aligned, a hole in each of the flanges are aligned and a lock may be attached thereto, securing the T-handle lock.

A door retaining device having particular application for preventing unauthorized removal of vending machine doors from vending machine housings. The door retaining device is fixedly secured at a first end to the vending machine door, and cooperates with the vending machine housing at a second end to permit rotation of the door relative to the housing about at least one hinge pin, but to substantially prevent movement of the door relative to the housing other than rotation about the at least one hinge pin. The door retaining device has a hook portion at the second end that extends into the housing through an aperture in the housing. The hook portion engages the housing to prevent movement of the door relative to the housing other than rotation about the at least one hinge pin.
