Cover an Oversized Cutout Around a Flush-Mounted Junction Box
This 6-inch oops plate—also called a trim ring or goof ring—covers the exposed wall or ceiling around a junction-box opening that was cut too large. It creates a cleaner finished appearance behind the installed light or camera fixture.
🌟 Why Choose This Oops Plate?
- Covers an oversized or uneven cutout around a flush-mounted junction box
- Two mounting slots retain the plate at the junction box
- White and black options coordinate with common fixture finishes
- Designed to sit behind common 4-inch and 5-inch fixture bases
📐 Fit and Dimensions
- Confirmed box types: flush-mounted pancake, octagonal, and PVC junction boxes
- Outside diameter: 150 mm (5.9 in)
- Center opening: 82 mm (3.2 in)
- Thickness: 2 mm (0.07 in)
Not for surface-mounted round junction boxes. The wall or ceiling opening must be smaller than the plate's 150 mm outside diameter and leave enough overlap to hide the cut edge. A full 6-inch opening will not be concealed.
📦 In The Box
- One 6-inch oops plate / trim ring in the selected color
🛠️ Installation
- Confirm that the junction box is flush-mounted and that the cutout is small enough for the plate to overlap the finished surface.
- Position the plate over the box and engage its two mounting slots with the junction-box mounting screws.
- Install the fixture according to its manufacturer's instructions, with the fixture base centered over the 82 mm opening.
⚠️ Before You Order
- This is a decorative oops plate only. It does not seal the opening or provide structural support.
- Verify that your fixture base fully covers the 82 mm (3.2 in) center opening.

I bought 4 of these to cover incandescent ceramic bulb fixtures in my garage which I had replaced with single gang outlets for new brighter lighting. The results were perfect and I am very pleased with the product.

Was not aware that the ring was 3D printed. I intended on using it as a decora ring for a light that did not fully cover the rim of the back box. This will not work and I would like to return it.
Thanks for your feedback. The listing clearly states that this item is 3D printed and designed specifically as a junction box cover ring, not a Decora trim ring.
