Enclosure comprises a plurality of bar members translatably attached to an interior surface of the door of the enclosure. Each of the plurality of bar members comprises a projection. A plurality of blocks are disposed on a peripheral edge of the opening of the enclosure's body, such that there is a corresponding block for each projection, and wherein each of the plurality of blocks define a channel for receiving and engaging its corresponding projection. When actuated in a first member, an actuator causes each of the plurality of bar members to translate between a first position and a second position. When the door is in a closed position, translation of the bar members to the first position causes each projection to engage with the channel of its corresponding block to thereby hold the door in the closed position. Translation of the plurality of bar members to the second position causes each projection to be translated out of engagement with its corresponding block such that the door can be opened.
