A wide variety of styles, steps, heights, and sizes allows you to custom fit this EGA Custom Work Platform System to your applications. Use a 3' wide platform by itself for safe access to elevated areas or add extensions to build a large deck that surrounds machinery or spans entire warehouse or shop. To create a level work deck, match platform and extension heights. If you need to reach different heights along your work deck, select higher or lower extensions for step-up or step-down levels. Extensions can only be added to models 73660, 73661, 73663, 73664, 76672, 73673, 73674, 73675, or 73676. Platforms may be raised or lowered 3".
