Where should support wires used for enclosure support in suspended ceilings be fastened?

Support wires used for enclosure support in suspended ceilings should be fastened at each end to ensure stability and adequate load-bearing capabilities. Fastening at both ends helps distribute the weight of the ceiling structure evenly and prevents sagging or drooping over time. This requirement is crucial for maintaining the integrity of the ceiling and ensuring that it is securely held in place.

Fastening only at the center could lead to uneven weight distribution, which might cause stress on the suspension system and potentially compromise safety. Similarly, fastening every 5 feet or just once per wire does not provide the necessary security and support that fastening at both ends does. Adequate support is vital for compliance with safety regulations and the overall performance of the suspended ceiling system.
