Cables and wires are housed in the upper tier, where they are completely isolated from the air stream. They are always up off the floor and easy-to-reach. Working on them always takes place in the ambient room environment. Because the wires are separated from the air stream there’s no need for costly plenum rated cables, which saves a lot of money.
The system is stringerless regardless of finished floor height and, without compromising structural integrity, an unlimited number of panels can be removed for fast, safe wire installation;
Wires and cables can be separated from each other in a variety of easy-to-install and easy-to-relocate modular cable trays. Overall it’s far safer and more flexible than using overhead cable tray.
There’s never a need to work on dangerous ladders. In the US there were 22,710 injuries and 161 fatalities in 2020 due to ladders.
