Meet the Jandorf 1-5/16 in. diameter rubber grommet — a purpose-built, insulating pass-through designed to protect wires and cables as they enter panels, enclosures, or equipment housings. This 2-pack delivers dependable edge protection in a compact, carded package that's ready for quick installs and stocking shelves.
Why this rubber grommet stands out
-
Exact opening size: 1-5/16 inch diameter opening (approximately 1.3125") to accommodate standard cable bundles and panel holes.
-
Solid edge protection: 3/8 inch depth provides robust cushioning where wires meet sharp edges, reducing abrasion and wear over time.
-
Durable insulating material: Flexible rubber delivers reliable electrical insulation while absorbing vibrations and minimizing wire movement.
-
Low-profile, professional look: Black color blends with most enclosures and disappears into the wiring harness for a clean, professional finish.
-
Value in a two-pack: Includes 2 grommets per card, ideal for multi-hole installations or stocking up for future projects.
-
User-friendly packaging: Carded packaging keeps parts organized and easy to store in a toolbox or supply cabinet.
Ideal use cases
- Electrical panels, control boxes, and equipment enclosures where wires must pass through metal or plastic walls safely.
- DIY electronics, hobby projects, and small machinery housings that require cable protection and strain relief.
- Speaker enclosures, AV racks, and light-to-medium industrial enclosures needing reliable insulation and edge protection.
Practical benefits and outcomes
By encasing the wire entry point, this grommet minimizes fraying, cuts, and heat transfer at the edge of the hole. The result is longer wire life, improved reliability, and a cleaner, more professional installation. Its insulating properties help maintain signal integrity and protect sensitive cables from incidental contact with conductive panel edges.
Tips for choosing and installing
- Before installation, verify the panel hole diameter matches the 1-5/16 inch opening for a snug fit.
- Insert the grommet so the flange sits flush against the panel to maximize edge protection.
- Route cables with gentle bends to maintain the grommet’s protective role and prevent kinking.
- For multi-cable runs, use the two-pack to cover adjacent holes or reinforce existing openings as needed.
