Thus far our largest opening: 8' X 8'

Checking to make sure the window works smoothly. And it did.

Screwing on the inside attachment board to be able to join two windows together. Worked great.

Getting the forearm straps in place to carry in the window. Piece of cake.

Ready to tip the window up to set in place.

Using a 2' X 4" X 8' to make sure the window stays inside the framing.

Four of the six windows are in place.
It took us about 30 minutes per window.
