The first step to an easy install is starting with a vent panel that fits snug to begin with.
Your custom window vent kit ships with an installation kit which includes strips of clear adhesive and glazier push points. (Strips of Velcro are not included, but are available to purchase on our order form.)
Clear adhesive tape holds well and removes easily when the season is over and you need to take it down.
Glazier push points provide a more secure mechanical hold, but are still very easy to install and remove.
See the installation methods for the three most common situations.
