Grommets

Grommets are protective inserts that line holes to guard cables, hoses, and fabric from sharp edges, vibration, and wear. They create a clean, finished pass-through, improve strain relief, dampen noise, and can block dust and moisture. From wiring in electrical panels to desk cable management and tarp reinforcement, hardware grommets boost safety, longevity, and appearance.

Choose from rubber grommets (EPDM, nitrile, neoprene, silicone) for flexibility, sealing, and temperature range; metal grommets (brass, stainless, nickel-plated steel) for strength and abrasion resistance; and plastic grommets (nylon, PVC) for lightweight and corrosion-proof use. Popular types include snap-in panel grommets, split grommets for retrofit installs, blind/closed grommets for sealing unused holes, strain relief grommets for cords, and furniture grommets with caps for desktops. For fabric, two-piece press-fit grommets/eyelets pair with washers to reinforce tarps, banners, and curtains.

Tips to get the right grommet and install it with confidence:
- Size accurately: match the hole diameter (ID), groove width, and panel thickness. Check a grommet sizes chart.
- Plan the fit: use split or two-piece styles to avoid disconnecting cables during retrofit.
- Match material to the job: EPDM for outdoor/UV, silicone for high heat, nitrile for oils, stainless for marine.
- Prepare the hole: drill or punch cleanly, deburr edges, and consider a step bit or knockout punch for accuracy.
- Improve sealing: look for IP-rated or flanged grommets to resist dust and moisture.
- Speed installation: a drop of soapy water or silicone lube helps snap-in grommets seat properly.
- For fabric: use a grommet kit with hole punch, anvil, and setter or dedicated grommet pliers.
