What Fits This Rough Opening?
Enter your opening size and see what will fit. We check it against the published size limits for every product currently on sale — the same limits the configurator prices against — and show the frame we would actually build.
ZIP is optional. Add it and the emailed copy carries the code numbers for your climate zone.
You get the result, not a newsletter. If it points at work worth doing, someone from our team will reach out to help.
This is a pre-check against our published size limits — not a quote, and not a site survey. It assumes the opening is square, plumb and structurally sound, and says nothing about the header, the sill, the flashing or what is behind the wall. Egress figures are estimated clear openings for the unit alone; sill height, grade and site conditions are what your code official rules on.
