5XPT SLIDING GLASS DOOR INSTALLATION INSTRUCTIONS
18. With the operable panel or panels open all the way, slide 14B2 sill wind load adapter into the
milled slot located in the bottom of the operable panel locking rail. (See Fig. 18) Slide into
the milled slot until the back end of the adapter clears the jamb. Push adapter down into the
reveal pocket extruded in the sill. The adapter should now slide back and forth in the reveal
pocket. An OXXO door requires two adapters, one for each panel.
With the adapter approximately 6” from the locking rail with the keeper or 12” between two
adapters of an OXXO door, close and lock the operable panel(s). This will automatically
locate the adapters. Open the operable panel(s) and approximately 6” from each end of the
adapter(s) apply a 1” to 2” long fillet bead of silicone. This will keep the adapter from
coming out of the reveal where it is positioned. (See Fig.19) Note: Before tightening the
adapters of an OXXO door, butt both wind load adapters together in the center.
Important: The 14B2 sill wind load adapter allows the operable panel to stay in during high negative
wind loads. Make sure that this adapter is firmly positioned in the sill reveal.
