Custom 60 x 80 Sliding Patio Door

Start with the opening. Then choose the operation, threshold and aluminum door system that make sense for your project.

01 / Find your route

One size request, three project paths.

A 60 x 80 request is a useful starting point. The information needed next depends on whether you are replacing one door, repeating a unit across a project or working toward a specified clear passage.

01 / REPLACEMENT

Fit the site you have

Record the existing frame, exposed opening, wall depth and threshold condition. Photos help show the existing frame and surrounding wall.

Next: measured widths and heights at multiple points.
02 / REPEAT UNITS

Keep the door schedule aligned

Group openings by size, handing, sill, glazing goal and delivery phase before selecting one system for repeated units.

Next: an opening schedule with quantity and location.
03 / CLEAR PASSAGE

Check the usable opening

The nominal width does not equal walk-through clearance. State the required clear width early, especially where accessibility rules apply.

Next: target clearance and applicable project criteria.
02 / Measurement basis

What does 60 x 80 actually measure?

60 x 80 inches is 1524 x 2032 mm. Tell us whether that size describes the site opening, the outside frame dimension or the existing door being replaced. Each custom door is sized to its project drawing.

  • Site openingMeasure width and height in several places; note wall build-up, floor levels and the old frame removal scope.
  • Door frameSet the overall manufactured width and height on the selected system drawing.
  • Rough openingCoordinate clearance, anchoring, flashing and tolerances with the installer and wall design.
Choose the panel direction, track depth and clear opening with your door system.
03 / Operation

Set the movement before the details.

Mark the active panel and opening direction from the exterior view. A two-track or three-track arrangement can change the frame, screen route and clear passage you can achieve.

Handing + panel countIdentify fixed and sliding panels on the opening schedule.
Clear width targetAsk for the usable passage in the selected arrangement.
Screen + lockLocate any screen and required locking hardware together.
Threshold routeRecord floor levels and outdoor rain exposure.

Clear passage depends on the frame, panel overlap and stop position. Ask for the usable width on the operating drawing.

04 / System short list

Find the right system for your opening.

Compare Q5, 135D, 135F and 143 by patio exposure, sill, glazing, panel movement and usable opening.

05 / Exterior interface

The threshold is part of the wall decision.

A low step can make passage easier, while an exposed patio needs a dependable rain route. Select the sill with the floor, flashing, drainage outlet and surrounding wall assembly in view.

  • 01Exposure: Is the door sheltered, at grade or open to wind-driven rain?
  • 02Floor line: What indoor and outdoor levels must meet the sill?
  • 03Drainage: Where can water leave the track and wall interface?

06 / Project performance

Choose performance for your location.

Share your project location, glass needs and thermal, air, rain and wind targets. Compare performance values for the proposed door size and configuration.

Glass & safety

Choose the glass build for the door location and ask for the required safety-glazing documents.

Thermal

Compare whole-door U-factor and SHGC for the proposed glass and frame.

Air, water & wind

Ask which air, water and wind test results apply to the proposed panel layout and door size.

Usable passage

Check the usable width at the fully open position on the operating drawing.

Local requirements

Share the project country, climate zone and code needs for the required documents.

Installation interface

Pair the door detail with the wall's flashing, drainage and anchoring design.

Add these performance targets to each opening in your door schedule.

07 / Project delivery
