The mechanism
How it works
A semi-cassette housing wraps the top and sides of the rolled fabric while leaving the underside open. That covers the surfaces that actually collect rain, leaves, and grit, at a fraction of the bulk of a full cassette.
This is the flagship for a reason: it is the only style built to custom width, from 9 feet 6 inches to 40 feet, with 8, 10, or 12 feet of projection. Openings wider than 20 feet are where an awning stops looking like an add-on and starts reading as architecture.
Integrated dimmable LED lighting runs inside the arms at no extra cost, EZ-Pitch lets you set the angle without tools, and a straight or sea-wave valance is removable if you prefer the cleaner line.

Why it's worth it
What this system gives you
The only style built to your opening rather than to a fixed size.
Dimmable lighting built into the arms, remote controlled, no extra cost.
Housing shelters the fabric surfaces that collect weather.
Change the pitch for sun angle or rain shed without tools.
Plus 300+ custom options, with removable straight or wave valance.
Non-prorated and transferable on hardware, fabric, and motor.
Ownership
Care & maintenance
Retract the awning in high wind, heavy rain, and snow — a wind sensor does this automatically and is the single best accessory you can add. Fabric awnings are designed to be retracted, not to fight weather.
Let the fabric dry before retracting when possible; rolling a soaked awning repeatedly invites mildew even on mildew-resistant Sunbrella. If you must roll it wet, extend it again to dry within a day or two.
Hose the fabric down two or three times a season and brush off leaves and pollen. Sunbrella cleans with mild soap and water; avoid pressure washers, which drive water into the seams and the roller tube.
Local fit
Built for Virginia, Maryland & DC
Virginia and Maryland summers put west- and south-facing decks out of use from about two in the afternoon. An awning is the cheapest square-footage you will ever add to a house, because it converts a deck you avoid into a room you use.
Our winters mean the awning spends months retracted. Anti-corrosion aluminum frames and a housing that shelters the fabric are what let it come out of March looking like it went into November — and it is why we steer most Mid-Atlantic clients toward cassette models.
