STITCH 20-LIFT SLIDING DOOR
Thermal barriers run through the frame section, separating the interior and exterior aluminum components.
Recessed locking points and the sinking compression seal provide a defined closing action along the door.
The sill section provides a drainage route beneath the track. Recessed thresholds are coordinated with the floor build-up and exterior drainage.
The locking point and lock seat are recessed into the frame and sash. The drawings below show how the door meets the surrounding structure.



Independent roller clusters support adjustment and access from the track.
Each roller unit can be adjusted to fine-tune panel alignment.
Roller clusters can be accessed and replaced through the track cover without removing the glass panel.
Straight, pocket and 90° corner arrangements are available within the system.


A corner layout brings two adjacent elevations into the same opening. The door configuration and building support are coordinated in the project drawings.


Plan panel parking, track recess and exterior drainage together.

Explore a screen configuration coordinated with the sliding panels.


Select the number of tracks and moving panels to suit the opening and the available stacking space.


Open the track cover to access leaves, dirt and other debris.

Explore entry lighting coordinated with the door system. The lighting layout and controls are specified for the project.



Electric opening is an available project option. Confirm the operating controls and power provision with the selected system.

Move the panels into a prepared wall pocket. Allow for pocket depth, panel parking and access before the wall is built.
Large glass panels paired with a lift-and-slide operating system.
A lift-and-slide operating system designed for large glazed panels.
Maximum sash weight: 881.85 lb. Capacity depends on the selected configuration.

Choose two-, three- or four-panel arrangements, with the moving and fixed panels positioned for your room.

Final sash sizes, track widths and floor details are confirmed in the project drawings.

Open adjacent sides of the room with a corner configuration. Coordinate the two elevations, panel parking and structural support together.

Different track arrangements can meet at an external corner, including two-track and three-track combinations.


An internal corner uses matching track configurations on both sides.


Slide the panel into a wall pocket to clear the opening. Plan the pocket space and service access as part of the surrounding wall construction.

Coordinate the handle finish and operating hardware with the selected door system.



Fold the panels to one side or split the opening into two groups. The Bi-folding 90 system pairs bottom load-bearing rollers with EPDM weather stripping.
| Operation | Folding to the left, right or split |
|---|---|
| Glazing options | Double or triple glazing with Low-E and argon |
| Sealing | EPDM weather stripping |
| Rollers | Bottom load-bearing arrangement |
Choose where the panels gather when the door is open. Configurations include 3, 4, 5, 6, 7, 8, 10 and 12 panels.
Panel count, handing and clear opening are coordinated with the available parking space.

Review installation depth and drainage for the selected floor transition.

Choose compatible handle and hinge options with your panel layout.

Explore neutral finishes, darker tones and custom colors for the aluminum frame.
Confirm the finish using a physical sample. Colors on screen may differ from the finished material.


Two panes with Low-E coating and an argon-filled insulating cavity.

Three panes with two insulating cavities, where the selected system accepts the glass thickness.
The glass build-up and Low-E coating are selected with the location, orientation and performance requirements in mind.
Discuss tempered glass, obscure glass and other compatible finish options for the opening.
The approved specification confirms the final glass thickness and coating.

Coordinate the screen with the sliding direction and the clear opening.
The illustrated system uses horizontal tension cords and bearings to guide the screen and handle bar.

Final screen size and compatibility depend on the selected door configuration.
