Although we all know the use of straight-through tray bridges, most people don't know what role he has, so let's let the editor introduce it to everyone.

1. Management role. In fact, this function is a simple management of the wires in the building. Through the straight-through tray bridge, the cables can be rationally planned and laid out, which can not only make the cables in the building more beautiful, but also save space.

2. Support. It is because of the use of straight-through tray bridges that the wires can be supported in the building.

3. Protection. This effect is quite obvious. After we use the bridge, we can play a good role in protecting the wires, which can isolate the cable from the external environment, thereby extending its service life and reducing failures.
