A port assembly (100) is generally disclosed that has an annular port ring (110) configured for placement in a barrier wall (10). The annular port ring (110) defines a port opening (20) extending from a first end (22) to a second end (24) and an annular sealing surface (118) about the port opening (20) on the second end (24). A port cover (120) is mechanically coupleable to the annular port ring (110). The port cover (120) defines an annular mating surface (124) configured to couple to the annular sealing surface (118) of the annular port ring (110). A manually actuatable handle (130) is in mechanical communication with the port cover (120). The handle (130) extends from the first end (22) of the annular port ring (110) away from the second end (24).
