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.
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.
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.
