Double Electric Trim Ring For Cabinet Cutouts

Double Electric Trim Ring is a black Fastcap grommet designed to clean up electrical cutouts in the back of cabinets, so finished installations look tidy where double gang boxes penetrate cabinet backs. The product is part of the grommets class, which means it surrounds the opening and provides a defined edge around the electrical box area. It is described as a double electric trim ring, so it is sized for a double box opening, helping keep the cutout consistent with standard double gang layouts. Fastcap lists this trim ring specifically for cabinet back applications, which focuses its use on cabinetry and similar casework rather than general wall openings. The black color provides a dark, uniform frame, which can visually tie into darker cabinet interiors or conceal minor cutout irregularities.

Key Double Electric Trim Ring Worksite Advantages

• The trim ring is designed to clean up electrical cutouts in the back of cabinets, so rough or oversized cabinet openings around boxes present a cleaner finished edge for customers and inspectors.
• The product is a Fastcap grommet, so it functions as a dedicated opening surround that protects the cutout edge while standard electrical components occupy the box area.
• It is identified as a double electric trim ring for double gang boxes, so it matches the footprint of a typical two-device electrical box used in many cabinet-backed installations.
• The trim ring is black, giving the opening a consistent dark frame that can visually recede in many cabinet interiors and help hide minor layout or cutting variations.
• The ring is part of a system that also covers single box sizes, so layouts that mix single and double boxes can share a uniform trim style from the same product family.

Electric Trim Ring Fit, Sizing, And Adjustment

The Fastcap Double Electric Trim Ring has a liner depth of 1-1/4 inches, so it can bridge typical cabinet back panel thicknesses while still surrounding the electrical opening. That liner depth can be trimmed in perforated 1/4 inch increments, which allows the installer to shorten the liner step by step until it sits flush with the back panel surface. Because the trimming is based on fixed 1/4 inch perforations, the adjustment steps are predictable, helping repeat the same depth cut on multiple cabinets in a run. The trim ring is easy to install and align with the Fastcap Outlet Stamp (FAOUTLETSTAMP), so marking and positioning the box opening on cabinet backs can follow a repeatable pattern before the trim ring is set in place.

Using This Trim Ring In Cabinet Projects

Where This Double Box Trim Ring Fits Best

The Double Electric Trim Ring, Black, is described as being designed to clean up electrical cutouts in the back of cabinets, so its primary use is in cabinetry where electrical boxes penetrate the rear panel. As a grommet in the multimedia and workspace components category, it suits installations where power, data, or other electrical devices sit in boxes behind cabinet interiors. The inside opening for the double box size is 5-5/16 inches wide and 5-5/16 inches tall, so it frames a roughly square double gang footprint at the cabinet back. Fastcap notes that the product comes in two sizes for single and double gang boxes, so this double version is best suited anywhere a two-device box is planned behind a cabinet or similar enclosure using a box of that type.

Why The Adjustable Liner Depth Supports Clean Results

The trim ring has a 1-1/4 inch liner depth that can be trimmed in perforated 1/4 inch increments, so installers can step the depth back cleanly to match varying cabinet back or panel buildups without resorting to irregular cuts. These discrete 1/4 inch steps allow the same depth setting to be repeated across multiple cabinets, supporting consistent reveal and alignment at every electrical cutout. Because the Double Electric Trim Ring is easy to install and align with the Fastcap Outlet Stamp (FAOUTLETSTAMP), layout and cutting can be coordinated with that stamp so the trim ring drops into a correctly sized opening with minimal fine-tuning. The double box inside opening dimensions of 5-5/16 inches wide and tall also give a defined target for cutting, which helps keep the visual margin around the box stable from one cabinet to the next.
