A grommet specified for a 1-1/4-inch mounting hole fits a nominal 31.75 mm cutout within its stated tolerances. Confirm the panel-thickness range and internal passage separately.
Check cable and connector clearance, groove geometry and flange overlap. Select the compound for temperature and fluid exposure, and verify any sealing or strain-relief requirements.
A grommet protects an intact cable at an opening; it does not restore exposed or damaged insulation. Stop using damaged wiring until it is appropriately repaired or replaced. Follow the equipment's cable-entry instructions rather than covering a damaged section with rubber.
