This Standard Door Mounted Pet Door is rated the best utility pet door on the market. No corners were cut - only the most durable products are used to make Security Boss Pet Doors. The frame of the dog door is crafted from heavy duty aluminum, and is available in white or bronze, to better match your design preferences. Choose anything from a small to extra large dog door - we’ve got you covered with 4 sizes to best fit your pet. This door mounted dog door fits doors 1 ¼” to 2” thick. The UV treated, fully weatherized vinyl flap won’t shrink, crack, discolor, or warp. Our unique design features metal strike plates riveted into this durable flap, which align with magnets inside the aluminum frame. These magnets combine with a dense pile brushing to create a firm, weather-tight seal. Need to fully block access? An HDPE blocking panel with twist-locking screw makes sure no human or animal is going in or out without your permission. A top-loading panel comes standard with this dog door - let us know if you’d prefer a side-loading one instead! Security Boss Pet Doors designs their pet doors with your ease of installation in mind.
