Buying Guide: Key Purchase Considerations
- Door compatibility: Confirm thickness range and whether the door is wood, metal, or PVC. Some doors fit 1.02″ to 2.36″ thick walls or doors; others offer adjustable tunnels.
- Material and durability: Aluminum frames resist rust and deformation better than plastic-only designs; metal welds and reinforced frames add long-term reliability.

- Locks and access control: Built-in closing panels or latches help prevent stray animals from entering and allow pet monitoring.
- Weight and installation: Heavy-duty doors can require extra mounting support; ensure mounting hardware suits your door type.
- Size and opening: Check flap width and height against your dog’s measurements to ensure comfortable passage.
- Warranty and service: Look for after-sales support, replacement flaps, and service terms for long-term use.
