Abstract: A scupper door system includes a frame defining a passageway. A door is mounted within the frame at a pivot and is therein rotatable about the pivot within the passageway between a closed position, blocking the passageway, and an open position wherein the passageway is open to permit passage of water therethrough. A latch mechanism is configured to retain the door in the closed position and is triggerable in response to a preset water condition at one side of the passage to release the door from the closed position and allow the door to rotate to the open position.

Abstract: According to one embodiment, a flood vent includes a frame forming a fluid passageway through an opening in a structure. The flood vent further includes a door pivotally mounted to the frame in the fluid passageway for allowing a fluid to flow through the fluid passageway. The door has two opposing faces that include a first face and a second face. The flood vent further includes a first float positioned within the door in a location in-between the first face and a second float. Additionally, the first float is configured to allow the door to pivot in a first direction. The flood vent further includes the second float positioned within the door in a location in-between the second face and the first float. Furthermore, the second float is configured to allow the door to pivot in a second direction.

Abstract: A vent barrier system may include an insert and a cover. The insert may be dimensioned to be inserted within a flood vent duct through a first opening such that side faces of the insert contact sidewalls of the duct and thereby provide an insulative seal between the first opening and a second opening of the duct when inserted therein. The may be configured to be attached to the insert and be dimensioned to be selectively securable to vent at the first opening. The cover may be manipulatable to selectively remove the insert from the duct.

Abstract: According to one embodiment, a flood vent includes a frame, a door, and at least one connector. The frame forms a fluid passageway through an opening in a structure. Furthermore, the frame extends into the opening in the structure in a first direction. The door is pivotally mounted to the frame in the fluid passageway, and allows a fluid to flow through the fluid passageway. The at least one connector is positioned between an outer perimeter of the frame and an inner perimeter of the opening. Furthermore, each of the at least one connector is configured to apply pressure to the inner perimeter of the opening in a second direction that is at least generally orthogonal to the first direction.
