Hello and thank you for taking the time to review this site. STR Products, LLC is a small business started and owned by myself. Currently our primary product is the Magnetic Mail Slot Door. I was inspired with the idea while installing a new entry door in our home in the middle of winter. A piece of flexible magnetic material was handy at the time to temporarily cover the mail slot hole from the cold outside. After seeing it in place the idea of making it permanent came to mind. The primary reasons I was disenchanted with door mail slots previously were energy inefficiency and appearance. My wife, however, insisted on having one due to the security and convenience. I have taken a great deal of time to research and prototype a quality product. The first model was tested on our door over the course of an 18 month period to ensure itsí capabilities. Our primary manufactures include one of if not the largest manufacture of flexible magnetic material and a reputable plastic extrusion manufacturer, both in the US. I personally inspect all packages before shipment. We are also working on a mail catch bag which attaches to your door and collapses if a wall restricts the area when the door is open. Again, thank you for the opportunity to share this product with you.
