Universal Thermostat Wall Cover Plate
A 150 x 104 mm wall plate that hides the paint shadow, old anchor holes and drywall damage left behind when a big old thermostat is swapped for a small smart one. A 36 x 26 mm centre opening passes the wire bundle and junction box, and 14 M4 clearance holes (4.5 mm) on horizontal 48/64/80/96 mm and vertical 44/60/76 mm spacings let it bolt to whatever pattern the new thermostat's subbase uses; a 5 mm standoff rim with a rib ladder keeps the 2.2 mm face flat against textured drywall.
