5XPT SLIDING GLASS DOOR INSTALLATION INSTRUCTIONS
11. The threshold and head filler are now ready for installation.
The head filler and the threshold are the same extrusion. The head filler will be finished to
match the door finish. The threshold will be clear anodized with a yellow protective cover.
This cover should not be removed and is there to protect the threshold and weather-strip
from construction damage.
The threshold protective cover needs to be removed to achieve full water
performance or when risk of damage is no longer present. Water may overflow the sill
with this protective cover in place.
The head filler and threshold are factory notched on both ends and shipped long for field cut
and installation. The end that will be next to the fixed panel meeting rail is the end that will
be square cut when cut to length. Figure the length of the threshold and head filler to fit tight
against the jamb and meeting rail. (See Fig. 7)
Important: Before measurements are taken for the cut length of the head filler and
threshold, be sure that the fixed panel’s indention mark is in proper alignment with the jamb.
(See Fig. 4 on Page 22 of 34)
An OXO will follow this same procedure. An OXXO head filler and threshold will be shipped
long and square cut on both ends. Follow this same procedure in determining the correct cut
length.
Position the head filler and threshold in place and drive on with a rubber mallet.
