Product Overview
Reliable custom rubber parts for industrial applications
Quick Answer
Eco-friendly star-patterned cable grommets are molded components for cable routing, panel hole protection, edge isolation and dust reduction. Outer diameter, cable opening, panel hole diameter, groove width, star slit pattern, material, Shore A hardness, color, tolerance and packaging can be customized according to drawings or samples.
The eco-friendly star-patterned cable grommet is a flexible molded component used to guide cables, wires or tubes through panel openings while reducing edge abrasion and dust entry. The star-patterned slit design allows cable insertion while helping the opening close around the cable. Material, dimensions, hardness, color, panel fit and packaging can be customized according to drawings or samples.
Eco-friendly Star-patterned Cable Grommet — Flexible Star-Cut Grommet for Multi-Cable Pass-Through
An eco-friendly star-patterned cable grommet is a flexible rubber cable management insert featuring a star-shaped slit pattern that allows multiple cables to pass through a single opening while keeping the hole neatly sealed. Unlike a solid single-hole grommet, the star pattern flexes open around each cable individually and closes back around the wire bundle to reduce gaps, dust ingress, and visible clutter on equipment panels or enclosures.

What Is a Star-Patterned Cable Grommet?
A star-patterned cable grommet uses a flexible, radially split (character-shaped) cut across its center opening, which lets several cables pass through one hole without needing a separate opening for each cable. This design lets cords be pushed into place from any direction, and the rubber closes back around them, keeping cables organized while reducing dust, debris, and moisture entry through the gap. A plain “through-hole” version without the star cut is also available for single-cable or pipe pass-through applications.

Why “Eco-friendly”
Eco-friendly versions of these star-patterned grommets are made from sustainable rubber compounds rather than rigid plastic alternatives, supporting easier end-of-life recycling since single-material rubber components are generally simpler to reprocess. Choosing a flexible rubber grommet also extends the service life of the product, as the star-cut slits can flex repeatedly around inserted cables without cracking, unlike brittle plastic cable covers that wear out faster.
Key Features
- Star-cut design lets multiple cables pass through a single opening.
- Flexible rubber construction returns to its original shape after cables are inserted or removed.
- Reduces dust, debris, and moisture entry compared with an open, uncovered cable hole.
- Wide size range from 12 mm to 80 mm inner diameter to suit small wiring up to large cable bundles.
- Through-hole variant available for single-cable or pipe pass-through needs.
- Eco-friendly rubber material supports sustainable sourcing goals.
Star vs Through-Hole Grommet
| Type | Best For | Notes |
|---|---|---|
| Star-Cut Grommet | Multiple cables or cable bundles | Flexible slits open individually around each cable |
| Through-Hole Grommet | Single cable or pipe | Solid center hole, no slit pattern |
Common Applications
- Electrical cabinets and control panels with multiple cable entries.
- Industrial machinery wiring pass-throughs.
- Server racks and equipment enclosures.
- General cable management in workshops and factories.
- Panel and wall pass-throughs where several wires exit from one point.
Sizing and Selection Guide
Selection should start from dimension B, the drilled hole size on the panel, matched against the grommet’s outer diameter (C) to ensure a snug fit. Dimension A represents the inner diameter reference for the star-cut opening or through-hole, which should be checked against the diameter of the cable bundle passing through. Dimension E, the total thickness, should be compared against the panel thickness to confirm proper seating and grip once installed.
Custom Manufacturing Options
- Custom inner diameter, drilled hole size, and outer diameter beyond the standard chart.
- Star-cut or plain through-hole pattern options.
- Custom rubber compound and eco-friendly material content.
- Custom color and packaging quantity.
- OEM branding and private-label packaging.
FAQ
What is an eco-friendly star-patterned cable grommet used for?
It is used to guide cables, wires or tubes through panel openings while reducing edge abrasion and improving cable routing. The star-patterned slit allows easier cable pass-through and helps cover part of the panel opening after installation.
Can the dimensions be customized?
Yes. Outer diameter, panel hole diameter, cable opening, groove width, flange profile, wall thickness and star slit geometry can be customized according to drawings or samples. Unsupported dimensions should not be assumed because panel fit and cable clearance depend on confirmed size data.
What does eco-friendly mean for this cable grommet?
Eco-friendly material requirements should be defined by the buyer before quotation. Options can be reviewed according to RoHS, REACH, low-odor material needs or other project-specific requirements. No certification or material claim should be assumed without confirmed documentation.
How should buyers select the material?
Material selection depends on temperature, flexibility, abrasion risk, cable movement, panel material, outdoor exposure, oil contact and compliance requirements. Buyers should provide the application environment and any eco-friendly material criteria so the compound can be reviewed correctly.
Is tooling required for a custom star-patterned grommet?
Tooling is usually required for molded grommets with a custom star slit, panel groove or flange profile. Tooling cost depends on the drawing and product structure. Existing tooling options can be reviewed after receiving the required dimensions.
Are samples available before bulk production?
Samples are available upon request. Sample preparation depends on grommet size, material, hardness, color, tooling status and inspection requirements. A drawing, 3D model, panel specification or physical sample helps confirm installation fit before batch production.
