ALL INSTRUCTIONS MUST BE READ PRIOR TO INSTALLATION
SET COLUMNS
Spacing and elevation of the columns are critical to the proper installation of the Mueller carport. The columns
must be square, plumb and set at the exact dimensions shown on the drawings. Depending on the direction of the
watershed, the high side columns must be 2 5/8” taller than the low side columns to achieve the appropriate pitch.
Particular attention should be paid to direction of the pre-punched holes in the top of the columns as shown in the
framing drawings (Holes in column must face to the center of the carport). Pack a small amount of dirt around
each column to temporarily hold them. Do not apply concrete at this time. Time and care should be taken on column
installation, as this will directly affect the appearance and ease of installation on the rest of the carport.

CROSS SQUARE THE FRAME (EXAMPLE)
Measure the frame corner to corner diagonally making sure both dimensions are the same. If not, pull the frame
square before starting sheeting. Commonly used tools are come-a-longs and ratchet straps. Squaring the frame is
critical to make the sheets run true on the frame and will affect appearance and ease of installation. Re-check level on
both P-1A purlins running column to column then add concrete and allow to dry.
