Identifying the type of vents you have
Your home may have a variety of vents. Below are names and pictures of the typical vents which you will find around your home.

Count and measure your vents:
Now that you have identified your vent type, it is time to count and measure them. The beginning of the below video “How to Measure, Cut and Prepare WDM” will take you through the process of measuring your vent and adding an additional inch to each side for the fixing of the mesh.
TIP: If you are unsure with your measurements, it's better to oversize the vent and use tin snips to trim it back during installation.
Safety
When you count and measure your vents, you may need to climb on a ladder or crawl into confined spaces. Please take proper safety precautions and if you feel uneasy, please contact one of the installers to assist you.
If you are unable to reach your vent, most smart phones will have a measurement app that will allow you to estimate your measurements from a distance.
