1'x1' White Plastic 3-way grille*damper*box,

Works perfectly. Customer service was very responsive to questions that I had.

I purchased a replacement for one that had broken. I have these installed throughout my home to accommodate central air. At seasons end I close the flaps on them to minimize cold air flowing into our home. A flap broke on the one I needed to replace. The replacement was very easy to swap out.
