In an indoor industrial setting, a stack of square metal tubes is suspended in the air by chains attached to an overhead crane. The tubes are painted black, and the cross-section of the stack reveals numerous individual square cavities. The crane moves the stack of tubes to the left, passing between a green door and a yellow metal platform. Debris and equipment clutter the floor, including barrels, hoses, and more stacks of tubes. The building has brick walls and an industrial ceiling.
