The configurator
Yes, a 144 × 96 opening can enter review.
Enter the actual opening instead of choosing a stock door. The width, height, panel count, stack, direction, threshold, frame, glass, finish, screen and project location remain together.
- Any positive width and height can enter feasibility review
- Panel count and stack direction stay visible
- Unsupported combinations return to documented quote review
- Shipping stays separate until packaging and destination are known
Measure once. Keep the record.
The opening schedule is the backbone of the order.
Use the same opening ID on the room, photos, measurements, structural review, panel plan, quote line, crate label and installation notes.

What buyers usually ask first
Can I request a nonstandard bifold-door size?
Yes. Enter the actual opening dimensions and preferred panel plan. The system, individual panel sizes, glass, hardware, threshold, structure and stack clearances are checked before a price is released.
Why are prices reviewed instead of estimated instantly?
Opening size, panel count, frame, glass, threshold, traffic door, screen, finish, freight and installation can all change the total. The reviewed quote matches the opening instead of presenting a stock price that may not apply.
Can I request product-only delivery?
Yes. Product-only, contractor, builder and installation-assisted projects can be reviewed. Delivery and installation depend on the system, crate, destination, access and project requirements.
Do you configure impact-rated bifold doors?
Impact projects can be reviewed, but the exact system, size, panel layout, glass, anchors, structure and approval must match the address and project criteria.
Can a screen or everyday traffic door be included?
Many configurations can coordinate a traffic panel and retractable screen. Their handles, housing, swing and panel stack must be planned together.
