Product Overview
Oblong cable grommets fit an elongated panel entry whose long sides meet curved ends. For this shape, overall length and width do not fully describe the fit. The end curvature and the way it joins the sides need to correspond with the molded retaining profile.
ETOL can customize dimensions, material, hardness and color, including silicone-oriented designs. Compare the finished cutout with the intended perimeter, then check the panel thickness held in the groove. A close fit along the straight portion should not require the end sections to stretch sharply into place.
Arrange the cable or bundle to use the available passage without loading only one curved end. The lead may shift toward an end when its external support is tightened, so inspect the entry after that step rather than stopping at the loose fit.
When inserting the grommet, work around both ends gradually and check for an inward-rolled lip. If the panel has limited access behind it, complete the seating inspection before nearby components are installed. During servicing, avoid levering at the narrow curved end with a sharp tool. Remove the rubber in a controlled way and inspect the entire groove before reuse, particularly where the straight and curved sections meet.
- Material options
- Custom silicone formulation and color for the specified shape and working environment.
- Hardness range
- 20–80 Shore A for silicone. Assess the grade against this fit requirement: A close fit along the straight portion should not require the end sections to stretch sharply into place.
- Custom profile & fit
- Compare the finished cutout with the intended perimeter, then check the panel thickness held in the groove.
- Assembly considerations
- If the panel has limited access behind it, complete the seating inspection before nearby components are installed.
- Design check
- The lead may shift toward an end when its external support is tightened, so inspect the entry after that step rather than stopping at the loose fit.
Photos illustrate structure or material only. Arrange the cable or bundle to use the available passage without loading only one curved end. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
