This web page has detailed instructions for easy installation

Kurt Shafer here, the inventor of this kit. I spent a lot of time looking into materials and sources and ways to cut the garage door openings. Here is what you will find that will make my kit easy to use.

  1. I am now selling thick plexiglass – 1/4 in with an option to get 3/8 inch. I can GUARANTEE they cannot be broken.
  2. I found a sheet metal cutter for you that works with any electric drill.
  3. I include rivet nuts that you install in the door.
  4. I have info on tools for rivet nuts that are very inexpensive and very easy to use.
  5. I have added instructions for you to understand how to use the tools.

So the total cost of tools is under $30 and the installation is very simple.

WHAT IS IN THE KIT

THICK PLEXIGLASS

First are the windows themselves. I found that when cut to 12 inches high and 16 inches wide then 4 of them fit in half of my 2 car garage door. 8 fit across the entire door. That is what you see in the picture above this page. And you get thick 1/4 inch plexi – did you know that is what is used on golf carts?

RIVET NUTS

These are incredibly useful because they attach the nut to your garage door so you don’t need another person inside the garage to hold a nut in place. Below you can see the result of the installation.

This is what the rivnut looks like after squeezing it with the rivnut tool.

The rivnut tool pulls a small threaded rod called a “mandrel” to squeeze the rivnut body against the sheet steel door.

8-32 PHILIPS HEAD SCREWS

The rivet nuts and screws are all threaded to #8-32 which means they are .164 inch in diameter with 32 threads per inch. These are easy to get anywhere. If you have a singlesided door it is thin like the picture above so the 3/4 inch long screws you get will be perfect. If you have a 2 sided door with foam insulation inside, you will want to get screws long enough to go through the thicker door. Below is a diagram of the installation in a thick door. You have the choice to cut a wooden spacer so that you can tighten the screws and not crush the foam in your door or you can put a thread locking fluid in the rivet nut to hold the screw in perfect tension without coming out.

Installation guide for cutting door

The door is cut using a “nibbler” that is driven by any electric drill you might have. Here is a picture of one in use by me.

Note this head is cutting at right angle to the drill center line

Tools you need are

  1. Nibbler to cut the door sheet metal.
  2. Rivet nut tool to squeeze the rivet tight in the hole you drill in the door.

NIBBLER – This dual head nibbler is perfect and low cost. I think you can find these for even less money.

Rivet nut tool- the one shown here needs a “mandrel” or threaded rod to thread into the rivet nut and squeeze it in the hole you drill in your door.
