🪟 Raised Edge Window Sill Extender Tray – Modular & No-Drill
Need extra window sill space with containment? This raised-wall extender tray is designed to sit securely on ¼” thick interior window sills, creating a clean, framed platform that helps prevent pots from sliding, tipping, or dripping onto your sill.
Unlike flat extenders, this version features raised sides on all four edges, with wall height matching the selected size so it sits flush beneath the window frame—without interfering with window operation.
