Cardinal Gates has been dedicated to making homes safer since 1992. Over the years the company has expanded from the original Hearth Guard to a full line of gates for children and pets. We strongly believe our gates are the best on the market in terms of safety ease of installation attractiveness and durability. We produce the only aluminum gates on the market which are light weight and able to weather the elements for exterior use. Our gates are constructed entirely of metal-we use no plastic parts-for additional strength and durability.We design all of our products and own a variety of patents on our gates and safety pad. These products are carefully inspected by hand in Newnan Georgia. This ensures that each gate meets our exceptionally high standards before we ship them out-we want them to reach their destination in as perfect condition as humanly possible. Additionally all of our gates are rigorously tested to earn the seal of certification by the Juvenile Protection Manufacturers Association.The Auto-Lock Gate (Model MG-15) A great gate for high traffic areas.
