The first instruction in the SunSetter Essentials installation manual is not about fabric, motors, or color. It asks the installer to walk outside and look at the wall: inspect the wall or soffit you plan to mount on, and be sure you have a clear area with no light fixtures, doors, windows, or downspouts to obstruct the installation. That ordering is the useful part for a US sourcing team. The document that decides whether a custom awning job goes well is not a width sheet. It is a risk-control brief, and it starts at the mounting surface.
Read as a model reference, and only as a model reference, that manual shows three acceptance gates worth carrying into an RFQ: mounting-surface clearance, partial-to-full projection behavior, and verification of the ordered size, color, and model. It says nothing about what any other factory can build. A single custom-size request is not a brief. It is a wish with a number attached.
A Custom Awning Brief Is a Risk-Control Document
A custom awning design brief is a pre-RFQ document that records three things: the mounting surface and what obstructs it, the projection positions the awning has to hold, and the size, model, and color the finished order must match. It is not a purchase order and not a drawing. It is the file a supplier reads to decide whether the job is buildable and which questions to send back before anyone quotes.
Those three items are where an awning most often fails to match expectation. Fabric and hardware get most of the attention in reviews. The failures that actually stop a project are an arm with nowhere solid to attach and a crate that arrives in the wrong size, and both are settled long before metal is cut. The Essentials manual is model-specific, so it does not tell you what an unknown supplier requires. What it does show is which checks a manufacturer puts in front of an installer, and those same checks belong in front of a supplier.
Mounting Surface Clearance Belongs in the Brief
The wall inspection line is short and specific for that series: a clear area, no light fixtures, doors, windows, or downspouts in the way. Turn it into three brief fields: which surface is being used, wall or soffit; what is already attached to it; and how far the clear zone runs. Photos with a tape measure in frame beat prose. A supplier reading that there is plenty of clear wall will ask anyway, and the answer arrives only after a second round of email.
Fabric weight, color, and motor choice belong in the brief as well, and no RFQ should go out without them. I would still hold the RFQ at the mounting line first. If the wall or soffit information is not in hand, waiting is better than letting a supplier quote against guessed dimensions, because a price built on a guessed mounting surface is a price for a different product. Quotes become comparable only when the site assumptions underneath them match.
What the line does not hand you is a clearance figure. It names obstructions for one series and stops there; it never states how much clear wall an awning needs. Any dimension a supplier offers for that should trace back to that supplier's own mounting instructions for the model being quoted, not to a manufacturer manual for a product you are not buying.
Projection Is a Range, Not One Number
Awnings get specified by width because width is what you measure against the house. Projection is what you sit under. The Essentials manual treats projection as a setting rather than a fixed dimension: once installed, the awning can be opened partially or to its full projection to suit the deck or patio design. Two things follow for the brief.
The first is that projection belongs in the brief as a set of positions, not one figure. Fully open for midday coverage, partway open when you want light without the glare sitting under the valance, closed when the space is not in use. A supplier who is told a single projection number has no way to say whether the hardware supports anything between fully open and fully closed.
The second is that width and projection are separate fields and stay separate. Nothing in a projection figure tells you the ordered width, and a width tells you nothing about how far the arms reach. A supplier who answers a width question with a projection number has answered a different question, and the mismatch usually surfaces at the first delivery. Ask instead for the projection positions the quoted model supports and what the mounting surface has to provide at full extension.
Three Revision Gates Turn a Request Into a Brief
Treat the brief as a document with versions rather than one long email. Version 1 is the request most buyers start with: a width, a projection, a color. It reads like an order and works as neither a brief nor a spec, because it carries no site information and no verification line, and every supplier who answers it fills the gaps with an assumption.
Version 2 adds the mounting-surface check, meaning the surface type, the obstructions, and the clear zone with photos. At that point the brief can survive a supplier's first round of questions without a phone call. Version 3 adds the two operating facts and the handoff line: the range from partial to full projection, and the order-verification line that has to be echoed on the quote and on the packing list.
Be clear about what these versions are. They are revisions of your document, not generations of a product. The Essentials material records no model years, no redesign dates, and no earlier hardware revisions, so nothing in this article should be read as awning history or as a claim that the series changed at any point.
Verify Size, Color, and Model at Handoff
The manual's pre-installation check asks the buyer to confirm that all listed parts came with the awning and that the size, color, and model are the ones ordered. That is a receiving check, and its logic applies earlier than receiving. Put three echo lines in the RFQ: the quote states those three fields as ordered, the packing list repeats them, and the crate label matches both.
Caught at the wall, a mismatch is a return shipment and a rescheduled install. Caught on the quote, it is an email. Order verification is not a capability claim, though. A supplier confirming that it will echo those order fields on paperwork has confirmed a documentation practice; it has not confirmed that it can build an arbitrary dimension. Keep those as separate lines in the brief so nobody reads one as the other.
The Tradeoff in a Stricter Awning Brief
A stricter brief costs calendar time. Site photos, projection positions, and an agreed echo line can push the first quote back by days, and a few suppliers will not engage with a document that asks for that much. What comes back is quotable: answers you can compare line by line against the checks the model manual already names, from suppliers who are pricing the same job.
Drop the gates and the process feels faster. Quotes arrive quickly, each priced against a slightly different guess about the wall, the projection, and the order paperwork, and the comparison you run is between numbers that were never measuring the same thing. I would keep the gates and take the slower front end. The trade is time, and the alternative is a purchase order signed against a size-only promise, with mounting clearance and order verification still open when the crate is on the driveway.
