Frequently Asked Questions

Which maxi pet door models does the G-SDDRF fit?

The G-SDDRF fits all five Catwalk® glass fitting maxi pet door models: G-SDDSLC (slim line clear), G-SDDSLW (slim line white), G-SDDC (dual glaze clear), G-SDDW (dual glaze white), and G-SDDB (dual glaze black). If you have the smaller glass fitting original cat door, you need the G-CDRF instead.

What is included in the G-SDDRF replacement kit?

The kit includes one replacement flap and one magnet for the bottom seal. The magnet ensures the flap closes securely and maintains a draught-free seal after each use. Step-by-step installation instructions are included in the downloadable PDF manual.

What is the difference between the G-SDDRF and G-CDRF?

The G-SDDRF is the larger flap for the maxi pet door range (G-SDDSLC, G-SDDSLW, G-SDDC, G-SDDW, G-SDDB). The G-CDRF is the smaller flap for the original cat door models (G-CDC and G-CDW). Always check your door model code before ordering.

When should I replace the flap on my maxi pet door?

Common signs include cloudiness or yellowing that reduces visibility, a weakened or failed magnetic closure, cracking or brittleness from UV exposure, or noticeable draught through the door. Replacing the flap is the most cost-effective repair and restores the door to full performance.

Do you ship the G-SDDRF internationally?

Yes. Pet-Tek International ships spare parts worldwide from Auckland, New Zealand. We supply customers across NZ, Australia, UK, Europe, the US, and beyond. Contact us to enquire about shipping to your location.
