Abandoned Spigot Wall Blanking Plate
A 110 x 110 mm wall plate that covers the hole left behind when an outdoor hose bib is moved or capped. It covers wall openings up to 68 mm across, and its hollow 45° dome clears a capped pipe stub up to 24 mm OD sticking out 22 mm (wider near the wall). It mounts with four slotted #8 screw holes (4.8 mm, 8 mm of radial adjustment). The back has a caulk-bead groove and a 4 mm weep channel so trapped water drains instead of rotting the siding.
