The Callowesse Extra Tall Pet Gate 7cm Extension fits seamlessly onto the Callowesse Extra Tall Pet Gate. This Safety Gate Extension allows you to extend the width of your gate up to 7cm. With the extension attached, it allows you to fit a safety gate into particular areas of your home with wider openings. Not all openings will fit safety gates, therefore, with the addition of an extension you can provide safety and security to your child, even within rooms that require a much larger safety gate. This Callowesse Extra Tall Pet Gate 7cm Extension is pressure mounted, so there is no need for drilling or screwing. Ensure you measure the opening within your home before hand to purchase the correct extension. This easy to use Extension securely fits into the end of your Callowesse Carusi Gate to provide a secure and confident fit. We recommend you fully read the Callowesse Extra Tall Pet Gate manual before installation.
