This is a perfect fix for thoes lowes or homedepot patio door dog door inserts. thoes inserts take up a bunch of room trying to get in and out your patio door not to mention all the heat or cold that you are loosing with the lack of a tight seal . these door conversions range from $700 to $2500 depending on what you need. i have done over 100 of them so i am well experienced on what it takes to make sure you get the best function and professional install for what you and your furry friend would need. (also do these in french doors) for more info call or text Tyson @(801 458 5932)
