Easy-Install 4-Mode Wall Pet Flap

A purpose-built, wall-mounted pet access solution made from rigid ABS plastic — selected for its balance of strength, light weight, and resistance to UK environmental stressors including rain, frost, and coastal salt air. Each unit ships fully assembled with size-specific flap dimensions and integrated weather stripping. The four available sizes — Small (18 × 18 cm), Medium (22 × 22 cm), Large (26 × 26 cm), and Extra Large (30 × 30 cm) — correspond directly to pet body width and standing height, ensuring natural gait and minimal head ducking. The locking mechanism uses a dual-slider design with positive click feedback, enabling reliable mode selection without visual inspection. 'Only In' prevents strays or wildlife from entering; 'Only Out' supports supervised garden time; 'Fully Locked' secures the flap during cleaning or travel; and 'Open' allows unrestricted flow. All moving parts are recessed and shielded from debris ingress. Suitable for both new builds and retrofits, it requires only a single rectangular cut-out in the wall — compatible with plasterboard, brick, stone, and insulated composite panels — and maintains wall insulation continuity when installed with included foam gasket and silicone sealant (not supplied but recommended).
