2-1/2 Inch Bore Hole Grommet For Wire Runs

2-1/2 inch bore hole grommet from Hughes Supply is a round wire grommet designed to finish and protect a 2-1/2 inch bore hole, so cable pass-throughs in desks, cabinets, or workstations stay clean and controlled. The H-0404-11009/B10 model is a grommet hole liner in white, which visually blends with light-colored surfaces and helps deliver a consistent look across a run of casework. Its role as a grommet hole liner is to shield the cut edge of the 2-1/2 inch hole, which matters for reducing abrasion on sheathing when wires pass through. The 2-3/8 inch inside diameter creates a defined channel for wires, which helps keep multiple cables grouped without binding tightly. The 3 inch overall diameter covers the cutout perimeter, which helps conceal minor chipping around the bore for a cleaner finished opening.

Key Grommet Hole Liner Details For Planning

• The bore hole diameter is 2-1/2 inches, which aligns with a 2-1/2 inch drilled opening and helps installers match boring operations to the finished grommet size for consistent layouts.
• The hole liner depth is 3/4 inch, which sets how far the liner extends into the panel and helps plan for material thickness and edge clearance in desks, cabinets, or panels.
• The inside diameter is 2-3/8 inches, which defines the actual pass-through space and helps estimate how many low-voltage or power cables can be routed through a single opening.
• The overall diameter is 3 inches, which covers the edge of the 2-1/2 inch bore and helps hide minor tear-out or tool marks around the drilled hole on finished surfaces.
• The product is described as white, which supports color coordination with light casework, shelving, or work surfaces where a neutral grommet appearance is desired.

Hole Liner Dimensions That Guide Installation

The 2-1/2 inch bore hole diameter ties directly to standard boring setups, so installers can match hole saws or bits to the specified opening and repeat the same size across multiple cabinets or tops. The 3/4 inch hole liner depth indicates how much of the grommet sits inside the panel, which helps determine suitability for common top and panel thicknesses without interfering with nearby components. The 2-3/8 inch inside diameter controls the working space for cables, helping plan how much wiring can pass through each location while still moving freely. The 3 inch overall diameter defines the visible footprint on the surface, which helps in laying out clearances from edges, adjacent cutouts, or hardware on crowded work surfaces.

Using This Hughes Supply Wire Grommet In Projects

Where This White Round Wire Grommet Performs Best

This white round wire grommet from Hughes Supply fits projects that call for a 2-1/2 inch bore hole and a clean, finished cable opening in desks, counters, or cabinetry. The grommet hole liner format focuses on lining the cut edge, which supports applications where the drilled hole needs protection as wires exit or enter a panel. With a 3/4 inch hole liner depth, the part suits panels where that depth can be accommodated without clashing with internal structures, making it practical for typical tops or vertical panels in multimedia and workspace components. The 3 inch overall diameter gives enough coverage to visually frame the opening on the finished face, which supports neat presentation in office, closet, or garage organization layouts using coordinated openings.

Dimensional Details That Support Consistent Results

The specified 2-1/2 inch bore hole diameter provides a clear target for boring equipment, which helps crews standardize drilling operations and avoid trial-and-error sizing on site. The 2-3/8 inch inside diameter offers a predictable clearance zone for routing wiring, which assists in planning cable counts per opening and positioning multiple grommets in series for larger harnesses. With a 3/4 inch hole liner depth, the grommet engages the panel edge along a defined length, which contributes to a stable fit in the bore when the matching hole is produced accurately. The 3 inch overall diameter defines the outer footprint, which helps designers space openings relative to adjacent edges, structural members, or other components so the grommet seats flat without overlapping nearby features.
