5XP 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 will need 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.
