What To Check

Why It Matters

Panel Opening

Cutout dimensions, corner shape, and trim depth

Panel openings vary between RV brands and switch modules

If your panel opening or dimmer switch differs from the photos shown here, reach out with a photo and we can help verify fit before you order.

Verify your opening

Check the panel cutout and confirm it matches the insert style shown. Make sure the surrounding trim has enough clearance for the finished face of the insert to sit flat and clean.

Test-fit before wiring

Place the insert into the opening before fully installing the dimmer switch. This makes it easier to confirm edge fit, switch alignment, and overall panel appearance.

Install the dimmer switch

Mount the 12V dimmer switch through the insert according to your switch hardware and panel setup. Tighten only enough to secure the assembly without distorting the printed part.

Confirm a clean finished fit

Once installed, verify that the insert sits flush, the dimmer turns freely, and the finished face covers the panel opening neatly without gaps or rocking.
