A fastening device for fastening a cover to a body of an explosion-proof enclosure can include a bracket having a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, where the top side includes an engagement portion, where the first angle is substantially parallel to an under side of the body flange, and where the second angle is substantially parallel to a top side of the cover flange. The fastening device can also include a cam fixedly coupled to an outer surface of the cover flange and hingedly coupled to the engagement portion. The fastening device can further include a lever fixedly coupled to the cam and having a closed position and an open position.

1. A fastening device for fastening a cover to a body of an explosion-proof enclosure, the fastening device comprising: a bracket comprising a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, wherein the top side comprises an engagement portion, wherein the first angle is configured to be substantially parallel to an under side of a flange of the explosion-proof enclosure, and wherein the second angle is configured to be substantially parallel to a top side of an opposing flange of the explosion-proof enclosure;a cam configured to be fixedly coupled to an outer surface of the opposing flange and hingedly coupled to the engagement portion; anda lever fixedly coupled to the cam and having a closed position and an open position,wherein the bracket is configured to engage the opposing flange and the flange when the lever is in the closed position, andwherein the bracket is configured to be disengaged from the opposing flange and the flange when the lever is in the open position. 2. The fastening device of claim 1, further comprising a securing device mechanically coupled to the top side of the bracket, wherein the securing device engages the lever when the lever is in the closed position. 3. The fastening device of claim 2, wherein the securing device comprises at least one detent that, when engaged, allows the lever to move into the closed position and hold the lever in the closed position. 4. The fastening device of claim 3, wherein the at least one detent is engaged by the lever when the lever moves into the closed position. 5. The fastening device of claim 3, wherein the at least one detent, when released, allows the lever to move out of the closed position. 6. The fastening device of claim 5, wherein the at least one detent is released by depressing a portion of the securing device. 7. The fastening device of claim 5, wherein the at least one detent is released by rotating a portion of the securing device. 8. The fastening device of claim 2, wherein the securing device comprises a spring clip that traverses an aperture in the lever and mechanically couples to the lever. 9. The fastening device of claim 2, wherein the securing device comprises a screw that traverses an aperture in the lever and mechanically couples to the top side of the bracket. 10. The fastening device of claim 9, wherein the screw is seated within an aperture in the lever. 11. The fastening device of claim 1, wherein the first angle is different from the second angle. 12. The fastening device of claim 1, wherein when the lever is in the closed position, a flame path is maintained between the opposing flange and the flange. 13. The fastening device of claim 1, wherein when the flange is part of the body of the explosion-proof enclosure, and wherein the opposing flange is part of the cover of the explosion-proof enclosure. 14. An enclosure comprising: a first enclosure portion comprising a flange;a second enclosure portion mechanically coupled to the first enclosure portion and comprising an opposing flange, wherein the opposing flange comprises a flange relief feature disposed along a distal end of the opposing flange and a proximal end of a normal portion of the opposing flange; anda fastening device mechanically coupled to an outer surface of the first enclosure portion, wherein the fastening device comprises: a bracket comprising a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, wherein the top side comprises an engagement portion, wherein the first angle is substantially parallel to an under side of the opposing flange, and wherein the second angle is substantially parallel to a top side of the flange;a cam fixedly coupled to the outer surface of the flange and hingedly coupled to the engagement portion; anda lever fixedly coupled to the cam and having a closed position and an open position,wherein the bracket engages the flange and the opposing flange when the lever is in the closed position, andwherein the bracket is disengaged from the flange and the opposing flange when the lever is in the open position. 15. The enclosure of claim 14, wherein the fastening device further comprises a securing feature mechanically coupled to the top side of the bracket, wherein the securing device engages the lever when the lever is in the closed position. 16. The enclosure of claim 14, wherein at least one selected from a group consisting of the flange and the opposing flange comprises a flange relief feature disposed continuously around a perimeter of the at least one selected from the group consisting of the flange and the opposing flange. 17. The enclosure of claim 14, wherein at least one fastening device is disposed along each side of the first enclosure portion. 18. The enclosure of claim 14, wherein the first enclosure portion is a cover, and wherein the second enclosure portion is a body. 19. An enclosure comprising: a first enclosure portion comprising a first flange and at least one mounting support;a second enclosure portion mechanically coupled to the first enclosure portion and comprising a second flange; andat least one fastening device mechanically coupled to the at least one mounting support, wherein the at least one fastening device comprises: a bracket comprising a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, wherein the top side comprises an engagement portion, wherein the first angle is substantially parallel to an under side of the first flange, and wherein the second angle is substantially parallel to a top side of the second flange;a hinged coupling feature hingedly coupled to the at least one mounting support and fixedly coupled to the bracket; anda lever fixedly coupled to the hinged coupling feature and having a closed position and an open position,wherein the bracket engages the first flange and the second flange when the lever is in the closed position, andwherein the bracket is disengaged from the first flange and the second flange when the lever is in the open position. 20. The enclosure of claim 19, wherein the first flange comprises a first portion having a first vertical profile that is less than that of a remainder of the first flange, wherein the bracket engages the first portion of the first flange and the second flange when the lever is in the closed position, and wherein the bracket is disengaged from the first portion of the first flange and the second flange when the lever is in the open position. 21. The enclosure of claim 20, wherein the second flange comprises a second portion having a second vertical profile that is less than that of a remainder of the second flange, wherein the bracket engages the first portion and the second portion when the lever is in the closed position. 22.
