The rivet nuts are easy to install using any rivet nut tool. Windows are 12 inches high by 16 inches wide. The picture shows mine with a 1-1/2 inch wide frame painted brown on the plexiglass to match my home trim. Cut an opening in each position you want a window. The recommended opening is 10 inches high and 14 inches wide which is perfect for a 1 inch wide painted frame to match your door color or your house trim.
Drill holes for the 4 rivet nuts using the recommended drill. Paint the edge in any color you want to look like a frame. Put a line of caulking around the back of the plexiglass and then hold up the plexiglass and put screws into each corner into the rivet nuts.
