How It
Works.
Model B installs with wall anchors into masonry or concrete. Each module covers 16" of width. Height adjusts up to 61" — no cutting required.
Model B can mount directly to the window frame or anchor into the surrounding masonry wall — whichever your surface requires. Both methods included.
Model B's upper section anchors to the masonry wall — the lower section telescopes down to match your window height, up to 61".
Model B anchored directly to the exterior masonry wall — one of the cleanest installs for stucco and concrete block homes.
Each Model B module ships in a compact box — fits in any car. No special delivery required.
Use the table below to determine exactly how many modules you need based on your window width.
| Window width | Modules | Max height |
|---|---|---|
| 16" – 31" | 1 | 61" |
| 32" – 47" | 2 | 61" |
| 48" – 63" | 3 | 61" |
| 64" – 79" | 4 | 61" |
| 80" – 95" | 5 | 61" |
| 96" – 112" | 6 | 61" |
