ABSTRACT:
An explosion vent comprises a symmetrical convex dome disposed over a building roof or wall vent opening. A pair of symmetrically arranged safety braces are disposed over the dome. A pin is disposed in each brace end and inserted in an enlarged opening or guide in a curb assembly which supports the dome on the building adjacent the vent opening. The pins and pin receiving openings or guides are arranged to disengage only when a predetermined pressure differential (an explosion) "pops out" the dome and braces in a predetermined direction determined by the parallel axes of the pins.
