The Badabulle gate is sold separately and is a pressure-mounted barrier with an auto-close gate. It's perfect for blocking off areas of the house that you don't want your children to go; maybe a kitchen whilst you're cooking or the stairs area. It's also an effective pet barrier. The gate is made from a mixture of sturdy and durable metal and features a one-handed opening in either direction and can stay open as required. The extensions allow you to make the barrier extra wide and are easy to attach before mounting the gate. The extension is sold in a variety of sizes, please measure the gap you wish to fit the gate in before purchase.
