ABSTRACT:
A shutter with an emergency exit has blocks attached to it. The projection of the blocks from the shutter match the projection of hinges that hold the emergency exit, such that the shutter winds evenly around a drum in a shutter box. The shutter also has reinforced horizontal shutter materials directly above and directly below the emergency exit to keep the shutter horizontally balanced as the shutter is wound into or out of the shutter box. The shutter also includes shock absorbing material where the emergency exit and the shutter meet. The shock absorbing material reduces noise from the contact of the emergency exit and the shutter and also prevents smoke from transferring from one side of the shutter to the other.
