Grommet & Blanking Plug Sizing — Quick Reference
Grommets protect cables and wires passing through panel holes (preventing chafing and insulation damage from sharp metal edges). Blanking plugs seal unused holes in enclosures. Selection turns on hole diameter, cable diameter, panel thickness, and material (rubber/nitrile for general; silicone for high temp; EPDM for outdoor/UV).
| Type | Hole Diameter Range | Material | Best For |
|---|---|---|---|
| Wiring Grommet (Champion CWG) | 4 – 50 mm hole | Nitrile rubber | Auto + marine panels, cable pass-throughs |
| Wiring Grommet (Assortment CA63) | 4 – 50 mm hole range | Nitrile | Workshop standard — sized hole + cable variety |
| Blanking Grommet (Champion CBG) | 4 – 50 mm hole | Nitrile rubber | Sealing unused knock-outs, junction boxes |
| Blanking Grommet (Assortment CA90 — 91pc) | 4 – 50 mm hole range | Nitrile | Panel-builder kit — common sizes ready-to-fit |
| Screw Grommet (Champion CBP12/CBP13) | Small bore (cable retention) | Nitrile + steel | Securing small cables — light fixing |
| Workshop Buddy Grommet Grab Kit | 1/8" – 1" hole (3 – 25 mm) | Rubber | 125-piece all-rounder workshop tray |
| Rubber Grommet Assortment (CA2174) | Mixed metric | Rubber | Maintenance + repair |
| Plastic Trim Clip (CA1735) | — | Plastic | Body + trim work — not for electrical |
Sizing rule: hole diameter = grommet OD groove; inner hole = cable OD; panel thickness = groove depth. Mismatched grommets either fall out or won't fit. Brands: Champion, Workshop Buddy. Companion: cable glands, heat shrink, cable management guide.
