window at the Head Jamb level. 
See Figure 1A and 1B. 
Record the measurement you took in Step 1.1. as the window Head Jamb 
opening width = W inches. 
The measurement you note (W inches) will be used as a reference of 
where to cut when cutting the Screen Cartridge Header and Pull Bar 
(A1/A2). 
Write the window's Head Jamb opening WIDTH measurement in Box 
W to the right for easy reference. 
In  Step  1.2.  below  you  will  mark  this  “W”  measurement  ON  the  Glued 
Measuring Tape Reference Guide (N) and CUT at the “W” inches NUMBER

differ from the width of your window opening at window Sill level. So be

the measurement of the width at your window's Head Jamb as your WIDTH 
measurement; “W” inches.

(A2) and Cut at your pre-measured “Width” inches mark. 
1.2.1. Ensure that the Screen Cartridge Header (A1 ) and Screen Pull Bar 
(A2) are aligned so they can be cut evenly at the same time.so as to be able 
to cut them both evenly at the same time. (See Figure: 1.2A) 
1.2.2. On the Screen Cartridge Header (A1) you will find a Glued Measuring 
Tape Template (N) pre-adhered to the Screen Cartridge Header (A1).

Cartridge Header (A1) at “W inches” ( the window's Head Jamb opening 
WIDTH measurement determined and recorded in Box W in Step 1.1. 
above).
1.2.3. CUT the Screen Cartridge Header (A1) and Screen Pull Bar (A2) 
contemporaneously AT the “W inches” width you
 determined as the Head Jamb WIDTH in Step 1.1.

Cartridge Header (A1).
