Name: Door Axis 75 Series Heavy Duty Aluminum Bi-Fold Patio Door System, Insulated Glass
Brand: Door Axis
SKU: DA-DR-PAT-FOLD75-3P-WS-SB

The Door Axis 75 Series Heavy Duty Aluminum Bi-Fold Patio Door System is a flagship folding glass wall built on a 2.95 in (75 mm) frame with a 0.079 in (2.0 mm) profile wall for large, hard working openings. It serves builders and homeowners who want tall folding runs, a choice of weather sill or low profile sill, and heavy duty folding hardware.

Panels run 27.5 to 37.4 in wide (700 to 950 mm) at system heights from 78.7 to 118.1 in (2000 to 3000 mm), with runs of 3, 1+3, 5, 3+3, and 7 panels that stack inside or outside the opening. A 2.20 in (56 mm) raised weather sill handles exposed, rain driven elevations, while the 0.63 in (16 mm) low profile sill gives a nearly flush indoor outdoor transition for covered openings. Stainless folding hardware with top and bottom pivots, intermediate carriers, and drop bolts moves the heavy leaves smoothly, and every system is fabricated to the opening size in one of eight standard finishes.

Installation Notes

Verify the structural header and opening squareness before release; heavy folding runs require a level, load checked head.
Install a sill pan and integrate flashing and waterproofing with the wall assembly; the 56 mm weather sill is recommended on exposed elevations.
Set the frame plumb, level, and square, then adjust carriers and drop bolts for smooth engagement across the full run.
Installation should be completed by a licensed contractor experienced with folding glass wall systems.
Confirm stacking direction, sill choice, and threshold transition during quote review.

Frequently Asked Questions

Which sill should I choose?
The 56 mm weather sill is the rainproof choice for exposed exterior elevations. The 16 mm low profile sill suits covered openings where a nearly flush transition matters. Both are confirmed during quote review.

Can the panels stack outside instead of inside?
Yes. Each run can stack to the inside or outside of the opening, and left or right stacking variants of every run are quoted during review.

Which finishes are available?
Eight standard finishes: Sand Black, Sand Gray, Snow Gray, Pure White, Fluorocarbon Champagne, Red Cherry, Golden Oak, and Black Walnut, applied as PVDF fluorocarbon or woodgrain film over extruded aluminum.

How tall can the system go?
Printed system heights run 78.7 to 118.1 in (2000 to 3000 mm). Taller custom work is reviewed case by case during quote review.
