Located at the meeting stile of the pair of AD-375 thermal doors are three
adjustable astragals. The exterior astragal has a single strip of wool pile
weathering. On the interior is located two astragals on opposing door stiles. These
are a thermal plastic with bulb gasket. Each of these astragals may be adjusted
independently to create an air tight seal. See instructions below for proper
adjustment.
Adjust astragal so that
piles lightly touch at
center of opening
Adjust astragals on each door
equally so bulb gasket lightly touches
at center line of door full length.
