A 100mm oval rubber grommet provides an elongated rubber interface for a cable opening. Structure, dimensions, material, hardness and color can be customized to match the panel and routed cables. Relate the nominal 100 mm reference to the complete oval profile, including both axes and the finished internal clearance.
Establish which dimension the nominal size represents before preparing the cutout. The full groove outline, groove width and outer flange footprint are needed to assess mounting fit. The cable passage must be considered separately, because rubber around the edge reduces the space available inside the panel hole.
For a large opening, look at how the bundle will be supported during installation. A group of cables resting against one end can pull a partly seated grommet loose before assembly is complete. Keep the weight supported while working the retaining edge into position.
Evaluate moisture exclusion with the selected cable arrangement and its supporting components in place. Any required sealing behavior depends on the chosen profile and the finished cable interface. Examine the whole perimeter after routing, and do not assume that a flat visible face means the concealed lip is fully seated.
Photos illustrate structure or material only. The full groove outline, groove width and outer flange footprint are needed to assess mounting fit. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
FIND THE RIGHT FIT
Choose a through-hole or blind-hole profile, then compare the dimensions for your panel and cable arrangement.
