Cable Hole Grommet Electrical Flat Ellipse Grommets

A Cable Hole Grommet for a flat ellipse opening protects a cable route with an elongated rubber liner. Both axes and the end curvature matter to the mounting fit. A rectangular measurement across the widest points is not enough to establish that a different oval profile will seat around the whole cutout.

Compare the opening shape with the retained region, then check the inside passage available after the rubber is installed. Keep a flat bundle within that usable space instead of pressing its edges into the curved ends. ETOL can customize the geometry, material, hardness and color for the required fit. During insertion, inspect the rounded portions where a lip can fold beneath the panel unnoticed. Once the cable is routed, confirm that the bundle does not pull one end outward or make the liner rotate. If a future connector needs to pass through, assess its actual orientation within the smaller internal opening rather than relying on the bare panel's longest dimension.

Material options

Custom rubber compound and color, selected for the contact conditions and required geometry.

Hardness range

30–90 Shore A for rubber. Assess the grade against this fit requirement: Once the cable is routed, confirm that the bundle does not pull one end outward or make the liner rotate.

Custom profile & fit

Compare the opening shape with the retained region, then check the inside passage available after the rubber is installed.

Assembly considerations

Both axes and the end curvature matter to the mounting fit.

Design check

During insertion, inspect the rounded portions where a lip can fold beneath the panel unnoticed.
