ABSTRACT:
A roof vent for preventing the buildup of hydrogen gas produced by battery charging in a remote digital telephone cabinet is provided with a movable splash guard for blocking the vent outlet when impinged upon by water and/or wind, thereby preventing the entry of water into the cabinet. The vent also includes a weatherproof cover whose lower edge is formed with scallops or undulations to maintain air gaps between the cover and the cabinet roof.
