4-1/4" pop-up desk grommet describes a Doug Mockett and Company, Inc. grommet and cap set that manages cords through a large round hole in a work surface, so power and data lines pass cleanly through a desk or workspace top. The cap and liner are sold together as a matching set, which keeps the opening sized correctly for the 3-1/2" bore hole diameter cited in the specifications. The overall 4-1/4" diameter of this grommet frames the bore hole cleanly, so the cutout edge is covered while still leaving room for cords and plugs to pass. The PU3-90 manufacturer part number ties this specific black grommet to Doug Mockett and Company, Inc., helping installers match it with existing project specifications. The product is described as a pop-up desk grommet set, aligning it with multimedia and workspace components where clean cord routing is a priority.
The specifications calling for a 3-1/2" bore hole diameter give the cutout size needed so the grommet liner seats properly in the desk or countertop. The 1-1/4" liner depth in the specifications shows how far the grommet extends below the surface, which matters when routing cords past structural members or shallow cavities. The 4-1/4" overall diameter in the specifications indicates the visible footprint on the surface, helping position the hole so it clears adjacent components. The twisting action described for setting the cap raised or flush means height adjustments rely on rotation rather than separate parts, streamlining on-site adjustments. The cap and liner being sold together as each set keeps installation focused on a single matched pair for each bore hole laid out on the job.
The product data places this item in multimedia and workspace components, so it suits routed openings in desks, tables, or similar worktops where cords and plugs need to pass through the surface. The description calling it simply a large round hole through which cords and plugs can be fed ties its use directly to power and data cord passages in office or shop environments. The 3-1/2" bore hole diameter supports installations in tops thick enough to accept a 1-1/4" deep liner, allowing the grommet body to seat into the material without exceeding the depth stated. The black finish named in the product name and SAP description identifies the visual appearance, so it coordinates with other black hardware and trim specified on the same workspace. The overall 4-1/4" diameter noted in the specifications makes this grommet appropriate where a larger cover is desired around the cord opening.
The PU3-90 manufacturer part number ties every unit to the same Doug Mockett and Company, Inc. design, so repeated installations can follow one cutout size and layout dimension. The 3-1/2" bore hole diameter in the specifications standardizes the cutting operation, which helps installers reproduce the same opening across multiple stations or panels. The liner depth of 1-1/4" defines how much clearance is required under the surface, so planning cord routing around framework or cabinets can follow that single depth value. The radiused cap design described for this grommet maintains a consistent rounded edge around the opening, which keeps the appearance and cord contact area the same from station to station. The description that the cap sits either raised or flush by simply twisting lets users set the cap position uniformly across several workstations, using the same rotation approach wherever this 4-1/4" pop-up desk grommet set is installed.
The 4-1/4" pop-up desk grommet uses a 3-1/2" bore hole diameter, so the installer bores that size opening for the liner to seat correctly.
The PU3-90 liner is 1-1/4" deep, so any structure or components beneath the surface need at least that clearance for the grommet body.
The Doug Mockett radiused cap design provides a rounded edge around the opening, so cords rest against a smooth profile instead of a sharp corner.
The web description states that the cap sits either raised or flush by simply twisting, so it can sit level with the surface when set to the flush position.
The specifications list a 4-1/4" overall diameter, so the visible cap and trim ring cover that width on the desktop or worktop.
The web description and packing detail state that the cap and liner are sold together as each set under manufacturer part number PU3-90.
This 4-1/4" pop-up desk grommet set from Doug Mockett and Company, Inc. combines a black radiused cap with a matching liner sized for a 3-1/2" bore. With the liner depth specified at 1-1/4" and the cap able to sit raised or flush by twisting, this PU3-90 desk grommet supports consistent cord routing layouts in multimedia and workspace projects handled through Wurth Baer Supply.
