4-Plug Junction Box Grommet For Clean Finishes

4-plug junction box grommet is designed to finish drywall, paneling, or furniture cutouts around wall-mounted junction boxes so exposed edges are covered and the installation looks deliberate. This Doug Mockett and Company, Inc. grommet is part of their multimedia and workspace components line, giving you a neat way to detail junction box terminations on built-ins or wall systems. The grommet is made for junction box applications where four outlets are present in a single square box, so it addresses typical 4-plug layouts in workstations or media walls. Its matte black color visually matches dark fixtures and trim, so the junction area reads as one unified element. As a grommet in the shelf, closet, and garage organization category, it supports organized power access points right where storage or workspace components meet the wall.

Key Junction Box Grommet Details For Pros

• The grommet is described as perfect for finishing off wall coverings or furniture around junction boxes, which hides rough cut edges and presents a clean transition between the junction box and surrounding surface.
• It is a four-plug junction box grommet for square junction boxes, so it aligns to standard 4-outlet layouts when planning media centers, workbenches, or similar multi-device locations.
• Four outlet box dimensions are 5-1/4 inch square outside size, so it fully overlaps the opening and surrounding material to conceal saw marks while keeping the junction area compact.
• The grommet fits into a 4-13/16 inch square hole, giving installers a clear target cut size that speeds layout, reduces guesswork, and supports consistent results across multiple openings.
• The lip on the grommet is 3/8 inch wide, providing enough bearing surface to cover minor chip-out at the edge of the cut while still sitting close to the wall or furniture face.

Square Junction Box Grommet Fit And Layout

This junction box grommet is sized for a 4-13/16 inch square hole, so installers can plan their cutout directly from that dimension for repeatable field work. With a 5-1/4 inch square outside size, the grommet overlaps the opening on all sides, so the junction box edge and cut line stay hidden behind the flange. The 3/8 inch wide lip around the perimeter provides enough coverage to mask small layout variances or blade wander, while still sitting tight to the finished surface so the junction does not look oversized. Because it is engineered around a four outlet junction box, its geometry supports typical 4-plug patterns used in media walls, office workstations, and garage or shop power points.

Using This Grommet In Real Installations

Where This 4-Plug Junction Box Grommet Excels

This 4-plug junction box grommet is positioned for wall coverings or furniture applications where a junction box penetrates a finished surface, so it is well suited to built-in desks, entertainment cabinetry, and utility storage runs. As a matte black component, it visually aligns with darker wall plates, shelving hardware, and garage or closet systems, so the power location does not visually dominate the installation. The grommet is part of a multimedia and workspace components family, so it naturally supports locations where multiple devices or tools plug into a concentrated 4-outlet box. Because it is classified under shelf, closet, and garage organization, it fits projects where power management is integrated into storage walls, shop stations, or closet islands. The square outside size of 5-1/4 inches is balanced against the 4-13/16 inch opening so the trim looks proportionate on both narrow panels and broader wall surfaces.

Fit Details That Support Consistent Cutouts

The grommet is specified to fit into a 4-13/16 inch square hole, giving installers a precise cut size that translates directly to jigs, templates, or CNC programming when repeating openings across a project. With a 5-1/4 inch square outside dimension, there is 3/8 inch of coverage from the lip beyond the cut edge, so even slightly rough or out-of-square cuts remain hidden once the grommet is seated. The stated 3/8 inch wide lip defines how close the opening can run to adjacent details like face-frame edges or panel seams while still maintaining full coverage. As a junction box grommet for four outlets, the internal opening is arranged to clear a square 4-plug junction box body, so the trim supports standard box geometry without interfering with outlet positions. The JB1-90 manufacturer part number provides a clear reference when matching this exact hole pattern and finish across multiple jobs or when repeating a successful layout on future projects.
