Most retractable porch gates are made with just plastic, but this deck gate is made with plastic and metal. Can you believe these gates even have a locking mechanism?! After you push, twist, and press the release button, you can easily extend the porch gate to the other side. When you release the handle your retractable deck gate will automatically lock. What’s super neat about this one is it’s UV and claw resistant. If you’ve got a scratcher, dog, or cat, these tough retractable mesh deck gates for pets, are one fantastic idea.
