Frequently Asked Questions

Which dog door models does the G-DDRF fit?

The G-DDRF fits all five Dogwalk® glass fitting Medium dog door models: G-DDSLC (slim line clear), G-DDSLW (slim line white), G-DDC (clear), G-DDW (white), and G-DDB (black). For the Intermediate (smaller) dog door range, see the G-IDDRF.

What is included in the G-DDRF 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-DDRF and G-IDDRF?

The G-DDRF is the Medium dog door flap (270 × 313mm) for the G-DD range, developed for medium to semi-large dogs. The G-IDDRF is the smaller Intermediate flap (216 × 250mm) for the G-IDD range, suited to small to medium dogs. Always check your door's model code before ordering to ensure the correct fit.

When should I replace my dog door flap?

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 full performance without replacing the entire unit.
