Hiddin's low Zig Zag Pet Gate is your alternative to the unattractive wood or metal pet gates that are unsightly and difficult to use. Our 24" high, freestanding pet gate is designed to confine your pet safely in areas with larger openings and comes in 4 stock sizes. Here is how to choose your gate size: The 4 Panel is for openings 56" or less. The 6 Panel is for openings 82" or less. The 8 Panel is for openings 110" or less. The 10 Panel is for openings 125" or less. Because it is 24" high, it is perfect for small and medium-sized dogs and is easy to step over. To set up, open the folding gate so that it spans the doorway, then rest the end panels against the doorway molding, on the same side as your pet. This setup prevents your pet from pushing the gate.
