Round Wire Grommets, 3/4" to 4" Bore Hole Two Piece Plastic - Doug Mockett And Company, Inc. OG3-90

Round Wire Grommets For Clean Cable Routing

Round Wire Grommets from Doug Mockett and Company, Inc. give you a simple way to route wires through work surfaces while finishing the cutout edge. This two piece plastic design uses a separate grommet cap and hole liner, so the liner covers the raw bore hole while the cap closes the opening. The cap has a permanent cut out for wires, allowing cables to pass through while the rest of the hole stays covered. Available sizes span from 3/4 inch bore hole diameter to 4 inch bore hole diameter, so the same product style supports small device leads or multiple heavier cables. The black finish identified in the description GROMMET+CAP, BLACK presents a uniform look on dark tops or panels. This OG3-90 part number ties directly to the described style, giving installers a specific reference when matching project standards.

Key Wire Grommet Details That Help Your Work

• This style grommet has two pieces; grommet cap and hole liner, so the liner seats in the bore hole while the cap finishes the opening and supports cleaner cable transitions.
• The cap has permanent cut out for wires, creating a defined path for cables that keeps the majority of the hole covered and reduces exposed substrate around the opening.
• Available in eight sizes from 3/4 inch bore hole diameter to 4 inch bore hole diameter, so a consistent product family can serve small electronics leads or larger bundles on the same job.
• The black color stated in GROMMET+CAP, BLACK ties the cap and liner appearance together, which supports a uniform look on dark desktops, counters, or panels.
• Packing is described as cap and liner sold together in full box quantities of 5 and 10, and Sold In full box quantities only, which supports straightforward counting for larger shop or site orders.

Installation Fit Based On Bore Hole Diameter

This plastic wire grommet is sized by bore hole diameter, so the opening you drill determines which version you use. The description specifies availability from 3/4 inch bore hole diameter to 4 inch bore hole diameter, which lets installers plan hole sizes around the cable load and the finished look. The two piece format means the hole liner drops into the bore hole while the grommet cap rests at the surface, so the liner hides cut edges and the cap defines the cable opening. Because the cap has a permanent cut out for wires, installers route cables through a fixed opening instead of an improvised notch, which can support more consistent results across multiple stations or panels.

Using This OG3-90 Grommet In Real Projects

Where Round Wire Grommets Fit Best In Workspaces

The OG3-90 designation identifies a specific style within Doug Mockett and Company, Inc. Round Wire Grommets, so specifiers can call out this part for repeat work. As a two piece plastic grommet with a cap and hole liner, it suits panel and worksurface applications where a drilled opening needs a finished edge. The liner occupies the bore hole diameter while the cap sits at the face, so the assembly visually cleans up the cut and frames the permanent cut out for wires. Because the product range covers eight sizes from 3/4 inch bore hole diameter to 4 inch bore hole diameter, a designer or installer can match the opening to the wire bundle size they expect at each location. The black designation in GROMMET+CAP, BLACK helps these openings recede visually on dark worktops, cabinets, or media furniture surfaces.

Why The Two Piece Design Supports Repeatable Results

This style grommet has two pieces; grommet cap and hole liner, which separates edge coverage from surface finish and can make layout more predictable from one opening to the next. The liner fills the bore hole diameter and hides the raw edge, giving the cap a stable, consistent seat at the surface. Since the cap has permanent cut out for wires, each opening maintains the same cable pass-through profile, which is useful when repeating a workstation or cabinet pattern. Having eight available sizes between 3/4 inch and 4 inch bore hole diameter means an installer can standardize drill sizes around known grommet options instead of improvising. The OG3-90 part number directly references this black grommet and cap combination, so documentation and reorders can specify the exact component used. Packing described as cap and liner sold together in full box quantities of 5 and 10 and Sold In full box quantities only supports straightforward, repeatable ordering for shop builds or site phases.
