Enclosure clamps and clamp systems are provided for fastening a cover to an enclosure body to provide an explosion-proof container, while minimizing the number of bolts used over conventional systems. The enclosure clamps and clamp systems create a sufficient force so as to provide a flamepath between the cover and the enclosure body. The enclosure clamps described include a channel for receiving the cover and a flange on the enclosure body. The enclosure clamp is secured to the enclosure body by one or more bolts and/or by a cam actuated securing mechanism. The clamp systems described include a force distributing plate secured to a cover by cam actuated securing mechanism that is coupled to an enclosure body. The enclosure clamps and clamp systems allow a user to attach or remove the cover from the enclosure body more easily than possible with conventional explosion-proof enclosures.
