ABSTRACT:
A smoke curtain assembly includes an extruded main supporting member permanently mounted in a ceiling structure, a smoke shield, and an extruded shield holder which is securely but removably attached to an upper edge of the smoke shield. The smoke shield is removably mounted in the main supporting member by tilting the smoke shield and lifting it and the attached shield holder through a slot-like opening between two upward extending flanges on the main supporting member. By shifting and straightening the smoke shield and the shield holder, the shield holder bridges the slot-like opening and downward extending flanges of the shield holder abut the upward extending flanges on the main supporting member to prevent lateral movement of the shield holder and smoke shield. When the shield holder and smoke shield are thus removably mounted, fasteners are included to prevent vertical and longitudinal movement.
