Compute total frame capacity needed to satisfy your load requirements.
Determine height required from floor to first beam or maximum beam spacing. If the figures
are different from our examples, use the next larger dimension.
3. Refer to bottom of Upright Capacity Chart. Reading left to right, locate dimension from floor to first beam or maximum beam spacing. From the beam spacing dimension, move vertically up the chart to weight capacity required for your maximum load. Moving to the right, locate the first upright capacity curve that intersects your required weight capacity. Follow curve down/across for correct upright post type.
Refer to ordering info. (light, medium or heavy-duty) for dimensional
information, and select from available sizes.
Choose light (L Post), medium (M Post), heavy-duty (H Post) or extra heavy-duty (X Post) upright to suit your storage requirements. Light-duty (13 gauge) upright posts are 3" (W) x 1-5/8" (D), while medium (13 gauge), heavy duty (12 gauge) and extra heavy-duty (10 gauge) upright posts are 3" (W) x 3" (D).
