Portico Rocker Switch Cover — Decora, Single
Cavetto House
Built for a Decora rocker on the correct 3-13/16 in strap-mount screw spacing, not the toggle plate's device spacing.
Oversized on purpose — covers the paint outline and drywall marks the old plate left behind.
Openings and screw positions stay in standard spec, so it still fits a standard box.
Made to order, printed individually in the finish you choose.

Why Portico
3.27 × 5.20 in
Single-gang size — oversized to cover the old plate's outline
3.5 mm
Face thickness, vs. ~2.3 mm for a stock plastic plate
60.325 mm
Standard device screw spacing — no non-standard fit
Openings and screw positions never move with plate size, so an oversized Portico plate still fits a standard box and takes the device's own screws.
Materials & Specifications
Matte PETG — printed at 0.16 mm layers, no gloss pass, so the six flutes stay legible
Screw fit — standard #6-32 wall plate screws; head countersunk 1.7 mm to sit flush
PETG rather than PLA because it does not soften in a warm room or go brittle with age.
How to Use
Cut the power
Turn off the circuit breaker for the switch or outlet you are replacing. Confirm dead with a non-contact voltage tester before touching any wires.
Remove the old plate
Unscrew the existing cover plate (usually one or two screws). Set the old plate and screws aside — you won't need them.
Seat the new plate
Position the Cavetto plate over the device. The opening should sit cleanly over the toggle slot, rocker face, or outlet slots. No trimming or adjustment needed.
Drive the screws
Use the original wall plate screws (#6-32). Tighten finger-snug, then one quarter-turn with a screwdriver. The countersink is designed for a flush, flat finish — do not overtighten.
Restore power
Turn the circuit breaker back on. The plate is complete — no painting, priming, or finishing required.
Pro Tip
If the plate rocks slightly, the device itself may be crooked in the box. Loosen the device's mounting screws, straighten by eye, and retighten before seating the plate.
Sustainability
Made to order means no overstock. Nothing is printed until you order it.
