An 8 mm closed rubber grommet covers a specified unused opening. Check the drawing to confirm the reference dimension, panel-thickness range and retaining profile.
A fully closed plug and a pierceable membrane are different constructions. Do not cut or convert a part unless its instructions permit the modification. If a cable must pass through, select a suitable passage or sealing profile.
Material choice and fit alone do not establish compliance with every safety requirement. Follow the installation instructions and verify any required sealing or mechanical performance for the application.
