    Description

    4-1/2" Grommet Set For 4" Hole Use

    4-1/2" grommet set for 4" hole, matte black gives you a matched grommet cap and liner sized for a 4" bore hole, so you get a clean, controlled cable pass-through in desks, counters, or work surfaces. The matte black finish keeps the opening visually quiet, which helps the grommet blend into modern multimedia and workspace components. This style grommet has two pieces; grommet cap and hole liner, creating a finished edge on the cutout while guiding wires through a defined opening. The cap has permanent cut out for wires, so cables follow a fixed path instead of wandering across the work surface. The set is part of Doug Mockett and Company, Inc. grommets, tying into a well-known hardware line for multimedia, shelf, closet, and garage organization projects where a 4" bore is already planned or installed.

    Key Grommet Details For Workspace Planning

    • This style grommet has two pieces; grommet cap and hole liner, so the cut edge of a 4" bore is covered and protected while cables pass through a smooth, consistent opening.
    • The cap has permanent cut out for wires, which channels cords in a fixed location and helps keep them grouped instead of spreading along the work surface.
    • The 4-1/2" grommet set for 4" hole, matte black is sized around a 4" bore hole diameter, supporting layouts that already call for that standard large opening in desks or worktops.
    • The matte black finish on the 4-1/2" grommet set for 4" hole, matte black coordinates with dark surfaces and trim, so the cable opening reads as part of the design instead of a distraction.
    • The grommet is categorized under multimedia and workspace components and grommets, aligning it with desk, closet, and garage organization layouts that route power or data lines through a work surface.

    4" Bore Grommet Fit And Installation Use

    The 4-1/2" grommet set for 4" hole, matte black is designed around a 4" bore hole diameter, so it pairs directly with that cut size during layout and drilling. This style grommet has two pieces; grommet cap and hole liner, which drop into the bore to finish the cut edge and hold the cap in position. The liner defines the circular opening, and the cap has permanent cut out for wires, so cables always exit through the same segment of the circle. That fixed cutout location helps align the bore with equipment, power strips, or wall penetrations, since the exit side is not variable.

    Using This Matte Black Grommet In Projects

    Where The 4" Bore Grommet Works Best

    The 4-1/2" grommet set for 4" hole, matte black fits projects that specify a 4" bore hole diameter in work surfaces or panels, giving those large openings a controlled finish. Its place in the multimedia and workspace components category ties it directly to desks, counters, and similar layouts where power and data lines must pass through a top. Shelf, closet & garage organization use is also supported by its category, so it can finish pass-throughs in storage panels routing lighting or device cords. The matte black finish coordinates with dark shelving, closet panels, or black-framed workstations, allowing the cable opening to sit visually with nearby hardware.

    Details That Support Consistent Wire Routing

    This style grommet has two pieces; grommet cap and hole liner, so once the liner is set into the 4" bore, the cap seats consistently and keeps the bore edge covered. The cap has permanent cut out for wires, and that fixed opening defines a repeatable exit point each time the cap is rotated into place. That consistency supports standard layouts where cables drop to a specific side of a desk or panel for connection to floor or wall feeds. The 4-1/2" grommet set for 4" hole, matte black works as a defined cable management point, since its large bore size handles multiple cords while the permanent cutout keeps them grouped. Being part of Doug Mockett and Company, Inc. grommets with manufacturer part ZG3-90 also helps maintain uniform appearance when several openings are used across the same installation.
