Drill proper holes into the walls for the side rails. Run a bead of silicone on the underside of the threshold piece (Image 1). Put it in place and tape it down until the side rails are in place (Image 2). Tap a plastic anchor into the pre-drilled holes in the tile (Image 3). Slide side rails into threshold (Image 4) and screw to the wall anchors with stainless steel screws (Image 5).
Place the glass stationary panel (Image 1), and slide it into the side rail. Attach the center rail and top rail to the side panel (Image 2).
Snap fillers into the threshold and the top rail where the swing door will go (Image 3).
