The Dreambaby Liberty 45cm (17.5") Gate Extension works with the Dreambaby Liberty Security Gate or Liberty Xtra Hallway Gate to extend the width of the gate. Extensions add versatility and many extra uses to safety gates. Extensions allow you to use gates all around the home, including in areas with wider openings. This adds extra safety for your young ones. Of course, not all hallways and stairways fit gate measurements - using an extension means that this does not jeopardize the security of your child, even in rooms which require a much longer partition. Safety gates are a very important part of at-home safety. They provide safe and secure boundaries for your children, preventing them from entering potentially dangerous or unsupervised areas of the home. * Measure the opening before deciding on your Dreambaby safety gate. * Simply attach the extension to your gate before installing.
