ABSTRACT:
Apparatuses and methods are provided for visual inspection across a barrier such as a fire door. In one embodiment of the present invention, a first movable partition is disposed adjacent, and laterally spaced from, a second movable partition. A first vision panel is disposed in the first partition and a second vision panel is disposed in the second partition in substantial alignment with the first vision panel. The position of the first vision panel is substantially constrained with respect to the position of the second vision panel along a first longitudinal direction. The first vision panel and the second vision panel are enabled to exhibit a desired amount of lateral displacement relative to each other.
