Single Electric Trim Ring White For Cabinet Cutouts

Single Electric Trim Ring white gives a clean edge around electrical cutouts in the back of cabinets, so finished work looks intentional instead of rough. This Fastcap trim ring is designed specifically to clean up electrical cutouts in cabinet backs, turning a raw hole into a defined opening that reads as part of the layout. As a grommet in the multimedia and workspace components category, it frames the opening around a single gang box while letting wiring pass through as planned. The white color helps the trim ring blend into typical cabinet interiors, providing a neutral surround that does not compete visually with wiring devices. Working from an established grommet solution means installers can repeat the same detail from project to project, rather than improvising each cutout finish.

Practical Details That Support Clean Cabinet Work

• The trim ring is part of Fastcap's electric trim ring line, so it is purpose-built around electrical box geometry, which helps the opening track more closely with single gang layouts.
• The single box inside opening dimensions are 3-1/2 inches wide and 5-5/16 inches tall, giving a defined rectangle to guide cutout sizing so the visible edge stays consistent.
• The product is identified as a grommet in shelf, closet, and garage organization as well as multimedia and workspace components, tying it directly to projects where cables and power routes pass through cabinet backs.
• The manufacturer part number ETR-SINGLE WH distinguishes this single-opening white version, helping shops call out the exact trim ring when repeating details or reordering for standard cabinet lines.
• The white finish pairs with typical light cabinet interiors, so the trimmed edge around the electrical cutout visually recedes and highlights the device or cable path instead of the raw substrate.

Cabinet Cutout And Trim Ring Fit Details

The single box inside opening of 3-1/2 inches wide by 5-5/16 inches tall sets the working target for the cabinet cutout, so installers can size and place the opening to match this trim ring. These fixed dimensions keep the visible reveal consistent around a single gang box across multiple cabinets on a job. The trim ring functions as a grommet, so it establishes a controlled perimeter where wiring passes through, instead of leaving the edge of the panel exposed. Matching the cutout to this opening helps reduce gaps around the box edge, which improves the finished look on both production and small-shop runs. Because this model is designated for a single box, it aligns the trim detail with that specific layout rather than a generic rectangle.

Using The Fastcap Trim Ring In Cabinet Projects

Applications Around Single Box Cabinet Openings

This Fastcap Single Electric Trim Ring, White, is aimed at cleaning up electrical cutouts in the back of cabinets, which is a common need in multimedia, workspace, and storage layouts. When a single gang box is mounted behind or through a cabinet panel, the trim ring creates a grommet-style surround that looks planned rather than patched. Its role within the grommets class connects it to cable and power management in shelf, closet, and garage organization, where devices, chargers, or equipment may draw power through cabinet backs. The defined inside opening of 3-1/2 inches by 5-5/16 inches helps align cabinet work with standard single box proportions, giving installers a reliable reference as they lay out cutouts on site or in the shop.

Adjustable Liner Depth For Consistent Results

The 1-1/4 inch liner depth on this trim ring can be trimmed in perforated 1/4 inch increments, so the installer can match the depth of the liner to varying cabinet back thicknesses or design needs. Each 1/4 inch perforation acts as a controlled break point, letting the liner be shortened without freehand cutting, which supports cleaner, more repeatable adjustments. This adjustability helps the trim ring sit correctly relative to the panel face, reducing the chance of a proud or recessed edge that would call attention to the opening. The trim ring is also described as easy to install and align with the Fast br Cap Outlet Stamp (FAOUTLETSTAMP), which ties it into a layout tool that sets position for the opening and streamlines the workflow from marking to finished trim.
