Step 1. Base Rail Assembly
Lay out base rails on grade level foundation (either floor slab or frost wall) as shown in Figure 2.

Place the column stubs into the channel of the base rails at a 90° angle as shown in Figure 1.

Add the front and back gable rails to the base rails. At this point, check all out-to-out dimensions of the base rail/gable rail assembly for conformance. Using the four (4) 90° Clip angles, attach gable rails to base rails with four (4) #12 Tek Screws (Figure 3). Periodically re-check all dimensions and alignments as the remaining base and gable rails are installed while carefully maintaining a constant parallel aisle dimension and equal diagonal (corner to corner) dimensions. These are critical to maintaining building squareness.

Step 2. Anchoring the Building
Either a concrete pad or a concrete frost wall is recommended to adequately support the building and its snow and wind loads. Whichever foundation is used, it must be true and level.

Use of Soil Anchors
Soil anchors can be used by the building purchaser in lieu of a concrete slab or frost wall foundation; however, TOIBOX STEEL STRUCTURES cannot assure adequate column anchorage because of the wide variability of soil conditions.

Should you decide to use soil anchors, site-specific soil conditions must provide a minimum of 2200 lbs. of "pull-out."
