Instructions
Preparation and Installation
Decide where to place the windows on your trailer. You can add windows on the sides, in the front of the trailer, or both. Purchase self-sealing ready mount windows in the size that best fits your trailer. There are many sizes and shapes available.
Draw the opening for the window onto the trailer with permanent marker. Use the window you purchased as a template. This will help to keep your lines straight when cutting.
Use a jigsaw to cut the opening for the windows. (The self-sealing ready mount slider windows have a flange of 3/8 inches for greater tolerance in the size of the rough opening, so don't worry if your cutting is not perfect.)
File off any rough edges on the window opening. Prime and paint the edges of the window to prevent them from rusting under the rubber grommet of the window.
Install the self-sealing ready mount window. As you install the window be sure the rubber grommet is smoothly covering both the inside and outside of the trailer to prevent any leaks.
