    Amazing Pet Door

    Posted by Monica on Oct 8th 2021

    This is by far the best pet door I’ve ever owned or seen. The quality of the aluminum and screen is top notch. It matches our newly installed pool cage perfectly. It blends so well that it took a few treats to convince our pups they could walk through it. This door is made of heavy duty but lightweight aluminum that matches the color and quality of our pool cage. The included security door is the heaviest and best built closure I’ve owned. It will keep all unwanted outdoor animals out easily. Due to COVID it will take some time for your order to be fulfilled. Our order took about 4 weeks to be fulfilled but once it shipped it arrived almost immediately. The contacts at Security Boss quickly replied to my email letting me know the expected ship date and explained the reason for the delay. Build in that time if you have project that is on a specific timeline. Overall we are very happy with this purchase and wouldn’t change a thing. Thank you Security Boss!

    SB4 Pet Screen Door

    Posted by Christine on Sep 5th 2021

    This is a very nice door. I had previously purchased one a number of years back and it is still in great condition. The only problem I experienced with this one is the entrance door had white screen on it and I don’t have white screen on my porch. I was able to change it out. The other thing I noted was the mounting screws were way too small for the installation. Otherwise this is a great door.

    SB4 Pet screen door

    Love this door! I just finished framing it into my Lanai, and it matches the bronze framing perfectly. It's super high quality and worth every penny. Now comes training the dogs and less running in and out for us! The instructions were spot on, most of the work was building the frame, not actually mounting the door, that was the easiest part. Thanks guys, love it and expect it will last a long time!
