Enhancing Design
Floor-Through-Door Sill:
The 4070-T Patent Pending sill design has been engineered for the 4400-T, making the home’s finished floor the door sill, leaving ONLY a slim slot drain. This feature is gorgeous and provides ample weather tested performance
Multi-Panel Option:
Not only is the 4400-T available in large widths, e.g. 12′, it can also be combined with several other panels for an even larger opening. With the ‘hold open’ feature of either the In-Rail (IRC) Floor Closer, these multi-panel openings are functional and dramatic.
Upper Floor Capable:
When the hydraulic In-Rail Closer (IRC) is chosen, the Series 4400-T is feasible for upper floors, which historically has not been possible due to limited floor depth. The pivot anchor only requires 1-¾” floor penetration.
Adjustable Closer:
Not only is the 4400-T available in large widths, e.g. 12′, it can also be combined with several other panels for an even larger opening. With the ‘hold open’ feature of either the In-Rail (IRC) Floor Closer, these multi-panel openings are functional and dramatic.
Upper Floor Capable:
The hydraulic In-Rail Closer (IRC) allows 3 custom operation adjustments:
- Open 90 Degrees Speed (slows down at 80-degree point)
- Final 30 Degrees Speed
- Final 10 Degrees Latching Speed
The three options are easily accessed from the underside of the bottom rail without removing the panel.

The “Little” Things
Residential Design:
In the aluminum pivot door world, only the 4400-T was designed for elite luxury residential applications. Competing products offer modified commercial doors that fail in performance and pale when comparing fit & finish.
Minimal Panel Stop:
One of many unique traits of the 4400-T is the beauty of the jamb and head panel stops. The stop slides into a concealed jamb groove and is attached from behind. When the stop is used in the head, the interior and exterior ends are finished with a cap.
Hidden Weather-Stripping:
During design, apt attention was given to hiding the needed weather-stripping as much as possible. The intention was for customers to only see aluminum and hardware while in a closed position.
