Panels stack beside the counter

Folding Pass-Through Windows, Configured Around the Opening

Choose where the open panels will go before settling the counter detail. Sliding panels stay on their tracks; pocketing needs a planned wall cavity; folding panels need a clear parking area beside the serving opening. Compare the actual system below, then review the counter, sill and reach.

Straight answers

Buying folding pass-through windows

Can I enter a nonstandard width and height?

Yes. Any positive dimensions can enter project review, including fractional sizes. The exact sash, panel, glass, hardware and fabrication limits are verified before a price or production size is approved.

Why is the final price not calculated from square footage?

Operation, sash or panel weight, glass, frame, sill, screen, controls, hardware, crate and freight can change independently of area. The quote uses a verified product configuration rather than an unsupported area formula.
