Abstract

A barrier door for a protective enclosure includes a lower section and an upper section. The upper section includes an outer stationary portion and an inner movable portion disposed within the outer stationary portion. The outer stationary portion and the inner movable portion are light transmissive. The inner movable portion is movable in a vertical direction and is coupled to a lift device disposed in the lower section. The lift device is configured to move the inner movable portion between a lowered position in which the inner movable portion is at least partially withdrawn into the lower section to form an opening in the upper section and a raised position in which the inner movable portion is extended to close the opening.
