Single Electric Trim Ring Black For Cabinet Cutouts

Single Electric Trim Ring Black is a Fastcap trim ring designed to clean up electrical cutouts in the back of cabinets, so the rough opening around a box ends up with a finished, consistent frame. The trim ring is part of Fastcap's electric trim ring line, which is made specifically for cabinet and woodworking applications where wires exit through the back. As a grommet-class component, it defines the edges of the cutout, helping keep the opening confined to the intended size. The black color visually blends around many electrical boxes in darker interiors, which keeps attention on the cabinet face instead of the cutout. Its single box format focuses on standard single gang layouts that need a clean transition at the back panel.

Key Trim Ring Details For Cabinet Work

• The trim ring is designed to clean up electrical cutouts in the back of cabinets, so installers can frame the opening after the box is in place and leave the interior looking planned instead of rough.
• Fastcap identifies this part as a single electric trim ring, which focuses the opening around one electrical box and simplifies layout for single gang installations in cabinet backs.
• As a grommet-class product in the multimedia and workspace components category, it manages the opening around electrical terminations, helping separate the box edges from raw cabinet material.
• The black finish ties into dark cabinet interiors or black electrical components, which can reduce visual contrast around the box and keep the cutout from standing out.
• The manufacturer part number ETR-SINGLE BL provides a consistent reference for reorders, so shops can match trim rings across multiple cabinet runs without re-measuring each job.

Cabinet Cutout Size And Liner Depth Details

The single box inside opening dimensions are 3-1/2 inches wide and 5-5/16 inches tall, which sets a clear template for the cabinet back cutout around a standard single gang box. Those fixed interior dimensions help installers size the hole so the box and trim ring align without excessive gap or material removal. The liner depth is 1-1/4 inches and can be trimmed in perforated 1/4 inch increments, allowing the ring depth to be reduced to match different cabinet back thicknesses or recess conditions. Because those increments are built into the liner, depth adjustments can follow the perforations rather than freehand cuts, supporting a cleaner edge around the interior of the opening.

Using This Fastcap Electric Trim Ring In Cabinets

Where This Single Trim Ring Fits Best

This Fastcap single electric trim ring is designed to clean up electrical cutouts in the back of cabinets, so it fits best wherever a single electrical box passes through a cabinet back panel. The single box inside opening dimensions of 3-1/2 inches wide and 5-5/16 inches tall match a defined opening, which helps align with single gang layouts that pass outlets or terminations through storage or multimedia cabinetry. As part of a grommet category focused on multimedia and workspace components, it serves well in cabinets that support electronics, workstations, or similar setups where cables and power run through the back. In these installations, the trim ring frames the box perimeter so the interior of the cabinet looks finished, which is useful for open shelving, closet systems, and garage organization where the back is visible.

Details That Support Consistent Cutouts And Alignment

The single electric trim ring has a liner depth of 1-1/4 inches that can be trimmed in perforated 1/4 inch increments, which lets installers adjust the depth to suit different cabinet materials while staying within the scored steps for predictable cuts. This adjustable depth helps the trim ring sit properly relative to the cabinet back instead of projecting too far into the storage space. Fastcap notes that it is easy to install and align with the Fast br Cap Outlet Stamp (FAOUTLETSTAMP), so when that stamp is used, the cutout placement is directly coordinated to the trim ring outline for more repeatable layouts on multiple cabinets. When combined with the defined inside opening dimensions, the installer can cut the same size opening across a run of cabinets and expect the trim rings to land consistently around single gang boxes.
