Sold Separately

Protective Screens—Screens (sold separately) create a barrier between you and hazardous material stored in a tank or hopper. Their openings are big enough to see through, but they won’t let tools or other objects fall in. Weld the brackets to the panel frame, then bolt the screen to the brackets. The screen won't fall out of the frame if it's jostled, but you can unfasten it if you need to access your tank.
