The Stromberg Carlson Econo Porch combines wide outdoor steps, a landing platform and a handrail that can be mounted on either side. This guide covers both the two-step EHS-102-R and three-step EHS-103-R, with the original assembly figures, hardware callouts and model dimensions.
EHS-102-R or EHS-103-R?
EHS-102-R — Two steps
EHS-103-R — Three stepsOriginal assembly figures
The Stromberg Carlson instructions show the steps folded for unpacking (Figure 1), the braces secured in their open positions (Figure 2), and the handrail bolted to the frame (Figure 3). Both models use the same assembly guide.
