Tension grid

From Wikipedia, the free encyclopedia

A tension grid is type of nonstandard catwalk. It is composed of a tightly stretched grid of steel cables that create a taut floor that is strong enough for technicians to walk on. Lighting instruments can be hung on a pipe grid just above the tension grid; there is no need for holes, as the light can shine through the grid, unobstructed, to the stage. Cables and electrical wires can pass through, and special fixtures may be used to allow beams and other solid material to pass through. This style of catwalk is popular in new and remodeled theatres due to the flexibility it provides.
