INSTALLING IN WINDOWS WITH TRIM!
By far the easiest and most popular way to install your new shelves!
Photos from a window in our office showing how a properly mounted unit should look in a window.
The 20" units are perfect for casement style or windows up to 24" wide.
The shelves are designed to utilize the free space inside the window well, only extending into the space a couple of inches.
Note how the angle bracket rests flat against the trim and how the shelves fill the interior of the window well.
