.
Y
X
b
. Round the length of the door panel (X) and the length of the astragal (Y) down to the
closest half inch. Subtract the rounded length of the door panel from the rounded length of
the astragal to determine your
index number.
Example:
To determine index number:
• If the astragal length is 79-1/4", round it down to
79
".
• If the length of the door panel is 75-3/4", round it down to
75-1/2
".
• 79" - 75-1/2" =
3-1/2
is the index number.
b.
Insert the tail cap onto the
narrow side
of the astragal body.
If drive rods are in the way of the cut down, slide further into the astragal or remove temporarily to
avoid damage to them.
