Short answer. For its specified A-Series 2-, 3-, and 4-panel gliding patio doors taller than eight feet, Andersen's frame-installation guide names two distinct interlock weatherstrips: one for the operating panel and one for the stationary panel. It also illustrates the two different component profiles. Therefore “the interlock” is a meeting-edge location, not proof that both panel pieces are identical.
Keep three identifiers separate
Panel position: Andersen defines A-Series unit handing from outside by the operating-panel location. source Seal position: its handing article places interlock weatherstrip between stationary and operating panels and categorizes interlock as non-handed. source Panel-specific profile: the tall-door installation guide separately pictures stationary-panel and operating-panel interlock components. Non-handed does not mean the two differently labeled components should be reversed or assumed interchangeable.
| Record this | Why it matters |
|---|---|
| Exterior viewpoint and moving-panel side | Establishes the unit-handing reference used by Andersen. source |
| Which of the two mating panel edges holds the damaged strip | Distinguishes the operating-panel and stationary-panel components in guide 9117014. source |
| Height, number of panels, original part information | The illustrated 9117014 guide is expressly scoped to A-Series 2/3/4-panel doors taller than eight feet. source |
Use the right document before naming a part
First locate the meeting line between the moving and stationary panels, then mark both edges in an exterior-oriented sketch. Compare the profile on each panel with the two differently labeled figures on printed page 4 of guide 9117014 BB (revised 01/25/23). Do not transfer the illustration automatically to shorter doors. source
Andersen installation guide 9117014 BB (revised 2023-01-25, printed p. 4) shows separate operating-panel and stationary-panel interlock profiles for specified A-Series gliding patio doors over eight feet tall. Determine which panel edge you are viewing and label it on a sketch made from the exterior side; do not treat the two illustrated pieces as identical.
A separate Andersen comparison article concerns historical 200 Series Perma-Shield two- versus three-panel configurations; those historical descriptions are not A-Series compatibility evidence. source
Choose an outcome
Located, not yet ordered: you can identify which mating panel edge is involved and find the exact diagram for the same series and size. Unclear: only a short loose strip or photo is available; request the correct model/size documentation first. Stop: the manufacturer's panel count, series, height band or guide revision does not match; no fit, slot, retrofit or interchange inference is justified.
Before ordering, confirm the A-Series product, panel count, tall-door height band and revision of the relevant manual. A shorter-door retail weatherstrip listing, including a similarly named interlock, is not evidence that its cross-section fits the illustrated taller assembly. Ask Andersen to identify the exact parts for the installed unit.
