    Enter Unit 2 Dimension:  in                     1 1" x 2" x .125" Aluminum Tube Mullion      
    Unit 1 & 2 Dimensions should include half of your mullion thickness.                           2 1" x 2" x .375" Aluminum Tube Mullion      
                              3 1" x 2.75" x .375" Aluminum Tube Mullion      
    Your Opening Dimension is:  in                         4 1" x 2.75" x .650" Aluminum Tube Mullion      
    Use only the dimensions of 2 directly adjacent units.                           5 1" x 3.125" x .500" Aluminum Tube Mull      
                              6 1" x 4" x .125" Aluminum Tube Mullion      
    Enter Loading Type (R or T):  R = Rectangular, T = Trapezoidal/Triangular;  See "Load Areas" tab or approvals for examples. If unsure, use Rectangular Loading.   7 1" x 4" x .375" Alum. Tube or "T" Mullion      
    The Mullion Design Pressure for the dimensions given above are shown for each mullion in the table on the right. Your selected mullion's Design Pressure must meet or exceed the opening's required Design Pressure. Choose a specific mullion, from the table at right, to determine the load transfered to the Mullion Anchors. Your Anchor options will be given in the table below.   8 1.25" x 3.188" x .265" Aluminum Tube Mull      
      9 1.25" x 3.25" x .100" Aluminum Tube Mull      
    Enter Mullion Type (1-16): Max. Design Pressure is:  psf Load on Mullion Anchors is:  lbs   10 1.25" x 3.25" x .624" Aluminum Tube Mull      
    Knowing Your Anchor Load, you can now choose the most appropriate anchor type from the table below.       11 1.25" x 3.94" x .624" Aluminum Tube Mull      
      Optional Design Pressure Reduction:                       12 2" x 4" x .25" Aluminum Tube Mullion      
        If your Mullion's Design Pressure is much higher than what your structure's opening actually requires, you may reduce the Mullion's Design Pressure. This lowers the anchor capacity required and could give you additional anchor options or require less anchors.   13 2" x 6" x .25" Aluminum Tube Mullion      
          14 1.26" x 2.11" x .125" Aluminum Tube Mull      
      Enter Reduced Mullion Design Pressure:  psf Your reduced Anchor Capacity required is:  lbs   15 3.25" 30 Degree Aluminum Bay Mullion      
                                      16 3.25" 45 Degree Aluminum Bay Mullion
