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. They strongly believe that their gates are the best on the market in terms of safety, ease of installation, attractiveness and durability. They produce the only aluminum gates on the market, which are light weight and able to weather the elements for exterior use. The gates are constructed entirely of metal-we use no plastic parts-for additional strength and durability.
