Dual-sided grommet kit

The FastCap dual-sided grommet comes in a pack of 100 black plastic pieces. Each unit includes both male and female ends so the grommet can be installed from either side of the panel. The 2.5 inch stem outside diameter fits holes up to 2.5 inches, making it suitable for cable pass-throughs in workshop, automotive or facility panels. Installers who need a finished edge on both faces of a sheet will find the two-piece design practical.

Thermals noise and power

As a passive plastic component the grommet generates no heat, draws no power and produces no noise. It simply lines the cut-out to protect wires from sharp edges and to seal the opening against dust or moisture. There are no moving parts, electronics or active cooling requirements to consider during specification or installation.

Build integration

The 3 inch lip outside diameter covers the hole cleanly while the 2.25 inch opening inside diameter provides room for cable bundles. Because the grommet is a standalone hardware item it needs no additional mounting hardware, power supply or control system. It frees up design time by eliminating the need to source separate male and female bushings, and the 100-piece quantity supports multiple panel locations or future maintenance.

Questions about this item

How do I install the 2.5 inch dual-sided grommet, and what step is often missed?

Push the male stem through the hole up to 2.5 inches, then snap the female end onto the stem from the opposite side; the step often missed is fully seating the female lip against the panel.

What maintenance or replacement will the black plastic grommets need over time?

Inspect the 2.25 inch opening for cracking or UV brittleness; replace any grommet that shows splits or has lost its grip on the panel.

What limit appears first when the grommet is used continuously in a 2.5 inch hole?

The 2.25 inch inner diameter restricts cable bundle size, so the first limit is the number of wires that can pass through without binding.
