Clear Weatherproof Pet Door Lock

External dimensions: 28 cm (W) × 25 cm (H) × 5.5 cm (D) / 11.02 × 9.84 × 2.17 inches. Frame and flap constructed from reinforced plastic — tested for repeated flexing and impact resilience. Transparent flap allows uninterrupted line-of-sight for pets, encouraging autonomous use without vocal prompting or owner assistance. Perimeter sealing strips compress evenly against door surfaces to limit airflow, water splash and ambient noise — particularly effective on older UK doors with minor gaps or uneven paint layers. Installs in under 20 minutes using standard Phillips screws; cutout required is rectangular with square corners — no router needed for most interior applications.
