5-1/2" Floor Access Grommet For Clean Wire Pass-Through

5-1/2" floor access grommet gives a clean, finished passthrough point in a 5" hole, so floor-based power and data feeds sit in a defined opening instead of an exposed cutout. The heavy-duty ABS durable plastic construction supports extra weight in floor applications, which keeps the opening stable in normal foot-traffic areas. Being made of ABS-KJW durable, flame resistant plastic in a black finish, it provides a consistent look while contributing to flame resistance in the penetration point. As a grommet in the Multimedia and Workspace Components category, it is suited to floor cable routing where wires need to exit in a controlled path. The Doug Mockett and Company, Inc. FG3A-90 design focuses on strength at the floor line so installers can rely on the trim piece to maintain a neat edge around the bore.

Key Floor Grommet Details That Support Daily Use

• Heavy-duty ABS durable plastic construction accommodates the extra weight for floor applications, which helps the grommet maintain shape and support when walked over or when furniture loads sit above the opening.
• The radius grommet edge helps avoid tripping over it, giving a smoother transition at the floor surface so shoes and casters are less likely to catch at the cable exit point.
• The double-thick grommet cover sits on a "step" inside of the liner for added strength, so the cover bears load more evenly and resists flexing when installed in typical floor traffic zones.
• The rotating cover allows snug closing with either one or multiple wires, letting installers adjust the opening size so cables are guided through while the remaining opening stays visually tight.
• The ABS-KJW durable, flame resistant plastic in a black finish offers both flame resistance and a dark, neutral appearance that blends with many floor and workspace color schemes.

Floor Access Grommet Fit And Installation Use Points

This floor access grommet is designed for a 5" hole, so it matches a commonly used bore size for floor cable pass-through work. The overall grommet is 5-1/2", giving an edge around the cutout that covers minor bore variations while presenting a finished flange. The radius edge around the grommet works with the 5-1/2" footprint to create a smoother profile at the floor surface, which supports safer movement around the penetration. Because the double-thick cover sits on an internal step inside the liner, the installation results in a layered structure where the liner bears the perimeter load and the cover reinforces the center area. The rotating cover function then completes the assembly, allowing the installer to orient the cable opening relative to wall or furniture layout.

Using This Floor Grommet In Workspace Cabling Runs

Where This 5-1/2" Floor Access Grommet Works Best

As a floor access grommet in the Multimedia and Workspace Components class, this part is suited to locations where cables need to route up from below the floor into work areas. The design for a 5" hole gives a predictable interface with floor penetrations that follow that bore size, which supports consistent detailing across multiple locations in a project. Heavy-duty ABS durable plastic accommodates extra weight for floor applications, so it fits use at desk clusters, conference areas, or equipment zones where carts and chairs regularly roll nearby. The radius grommet edge that helps avoid tripping over it further aligns it with pedestrian areas, because the transition from flooring to grommet is gentler than a sharp-edged ring. With the black finish, the floor opening reads as a defined, dark circle that visually recedes in most office or shop flooring palettes while still clearly marking the cable exit point.

How Design Details Support Repeatable Floor Penetration Results

The double-thick grommet cover that sits on a step inside the liner creates a nested structure where the liner supports the perimeter and the thicker cover strengthens the visible center area, giving the opening a solid feel under typical loads. This stepped seating also helps keep the cover aligned within the liner, which reduces wobble and helps the rotating cover track smoothly as it is adjusted for one or multiple wires. The rotating cover feature allows a snug closing around cables, so the opening can be oriented toward the equipment while unused sectors remain closed, helping organize cable exit paths. Because the material is ABS-KJW durable, flame resistant plastic, the combined liner and cover structure contributes flame resistance at the penetration point while maintaining structural integrity. Designed by Doug Mockett and Company, Inc. as model FG3A-90, the part follows a consistent geometry that supports repeatable installation results across multiple floors or rooms.
