    Cat Flap in a Rockdoor Anthracite Grey Door

    Rockdoor's Anthracite Grey is the UK's single most popular composite door colour — a deep near-black grey that pairs with almost every window frame and render finish.

    Fitting a cat flap into a Rockdoor Anthracite Grey composite is one of our most common jobs — the darker colour hides any residue from the cut line perfectly, and the carbon-fibre reinforced core cuts cleanly when the right tools are used.

    Recommended flap for this colour

    SureFlap Microchip Cat Flap (Brown)

    The brown SureFlap frame reads as near-black against Anthracite Grey and disappears into the door line — a white flap would jump out.

    Why colour-matching matters: a well-matched flap frame is the single biggest visual factor in whether an installation looks intentional or added on. We include colour-match advice in every quote — no cost, no obligation.
