quality material and visibility: made of clear acrylic, this home dog door is rust and corrosion resistant compared with traditional metal or wooden doors. The transparent design provides a 360degree view of the surroundings, which helps reduce your pet's anxiety. Flexible, humanized design: the assembly uses 6 panels with a height of 24 inches and a maximum unfolded width of 120 inches. Panels are connected by preinstalled 270degree rotatable hinges, allowing easy shaping to fit your space. Each panel features a handle on for portability, so you can move it where you need it. Safe and stable for pets: acrylic fencing has impact resistance, so doorways and play areas stand up to pet activity. Edges are smooth to prevent snagging or injury, and the design helps prevent pets from climbing. It's gentler on teeth and claws than traditional iron fences, making it suitable for puppies, kittens, or bunnies. Easy to use and clean: unlike metal fences, it cleans quickly with a damp cloth and water. You can adjust the size of the enclosed area by changing the folding angle of the panels to suit your space and pet needs. Practical use scenarios: Create a safe, contained play area for a puppy in a living room or open area while keeping them visible. Block off stairs, kitchens, or other restricted zones to prevent access, while still allowing your pet to observe the surroundings. Divide larger rooms or apartments to manage multiple pets or to shield delicate areas, with the shape easily customized to fit doorways or unusual layouts.
